I am trying to add weapons to a player inventory. It's kind of hard to explain, so I'll try my best. What I have are a class for each weapon, a class for Combat, and a class for the Player. I am trying to get it to where when the Random number equals a certain number, it will add a weapon to the player inventory. I will put my code Below.
Combat Class:
public class Combat {
M4 m4 = new M4();
M16 m16 = new M16();
M9 m9 = new M9();
Glock glock = new Glock();
SCAR Scar = new SCAR();
Player player = new Player();
final int chanceOfDrop = 3;
static boolean[] hasWeapon = {false, true};
public static int ranNumberGen(int chanceOfDrop) {
return (int) (Math.random()*5);
}
private void enemyDead() {
boolean canDrop = false;
if(ranNumberGen(chanceOfDrop)==0){
canDrop = true;
}
if(canDrop == true){
if(ranNumberGen(0) == 1) {
Player.addInvetory(m4.weaponName(wepName), m4.weaponAmmo(wepAmmo)); //Issues here. wepName & wepAmmo cannot be resolved into variable
//Should I just delete the line?
//Trying to get it to add the weapon M4 to the player inventory.
//Maybe use an ArrayList? If so I need a couple pointers on how to implement this.
}
}
}
}
M4 Class:
public class M4 implements Armory {
//Weapon classes are practically identical except for differences in the name wepDamage and wepAmmo.
public Integer weaponAmmo(int wepAmmo) {
wepAmmo = 10;
return wepAmmo;
}
public Integer weaponDamage(int wepDamage) {
wepDamage = 5;
return wepDamage;
}
public String weaponName(String wepName) {
wepName = "M4";
return wepName;
}
Player Class:
public class Player {
public static int health = 100;
//Player Class.
public static void addInvetory(String wepName, int wepAmmo) {
Player.addInvetory(wepName, wepAmmo);
}
public static void removeInventory(String wepName, int wepAmmo) {
Player.addInvetory(wepName, wepAmmo);
}
public static void removeAll(String wepName, int wepAmmo) {
Player.removeAll(wepName, wepAmmo);
}
Interface:
public interface Armory {
//Interface implemented by all of the weapons classes.
public Integer weaponAmmo(int wepAmmo);
public Integer weaponDamage(int wepDamage);
public String weaponName(String wepName);
Hope you can help!
class Weapon {
private final String name;
private final int damage;
private final int ammo;
public Weapon(final String name,final int damage,final int ammo) {
this.name = name;
this.damage = damage;
this.ammo = ammo;
}
public Weapon clone() {
return new Weapon(this.name,this.damage,this.ammo);
}
public String getName() {
return this.name;
}
public int getAmmo() {
return this.ammo;
}
public int getDamage() {
return this.damage;
}
}
class WeaponFactory {
static WeaponFactory factory;
public static WeaponFactory getWeaponFactory() {
if(factory == null) {
factory = new WeaponFactory();
}
return factory;
}
private ArrayList<Weapon> weapons = new ArrayList<Weapon>();
private Random random;
private WeaponFactory() {
//TODO: Fix Ammo and Damage
weapons.add(new Weapon("M4",0,0));
weapons.add(new Weapon("M16",0,0));
weapons.add(new Weapon("M9",0,0));
weapons.add(new Weapon("Glock",0,0));
weapons.add(new Weapon("SCAR",0,0));
}
public Weapon getWeapon() {
int w = random.nextInt(weapons.length);
return weapons.get(w).clone();
}
}
class Combat {
...
private void enemyDead() {
if(ranNumberGen(chanceOfDrop)==0){
Player.addInventory(WeaponFactory.getWeaponFactory().getWeapon());
}
}
}
You can use an array of Armory and the generate a random number from 0 to the size of the array as an index to the array to decide which weapon to add.
Okay dude, since your question about creating a programming language was closed, I'm answering it through here:
I think that your idea is great! Don't give up on it, yet don't get too excited. I would try all the options that you have heard of(interpreted route AND the Compiled route). If you can get either of those to work, then you may proceed to go into further detail with the language creation. It's going to take a while though. Be patient!

I am trying to sort an ArrayList in increasing order in reference to a certain variable. This is the problem question.
q5: Create a public class named Snow with private instance variables vast, prior, ethnic, and remarkable each of type int. You may add any other methods and variables you'd like to this class.
Outside of Snow (in the Problem Set class) write a public static method named sortSnow that takes an ArrayList of Snows as a parameter and returns void. This method will sort the input by the variable remarkable in increasing order
This is what I wrote.
public class snow implements Comparable<snow> {
private int vast;
private int prior;
private int ethnic;
private int remarkable;
public snow( int vast , int prior, int ethnic ,int remarkable) {
this.vast=vast;
this.prior = prior;
this.ethnic = ethnic;
this.remarkable = remarkable;
}
public int getEthnic() {
return ethnic;
}
public void setEthnic(int ethnic) {
this.ethnic = ethnic;
}
public int getPrior() {
return prior;
}
public void setPrior(int prior) {
this.prior = prior;
}
public int getVast() {
return vast;
}
public void setVast(int vast) {
this.vast = vast;
}
public int getRemarkable() {
return remarkable;
}
public void setRemarkable(int remarkable) {
this.remarkable = remarkable;
}
public int compareTo(snow compareSnow) {
// TODO Auto-generated method stub
int compareThese = ((snow) compareSnow).getRemarkable();
//ascending order
return this.remarkable - compareThese;
}
}
public static void sortSnow(ArrayList<snow>input){
Collections.sort(input);
}
I am not understanding what the error means. The autolab is giving me this error:
Could not find class submission.ProblemSet$Snow
Java is case sensitive i.e. snow is not Snow is not sNoW. Rename your class to Snow and try again. Also, it is ArrayList and not arraylist.
Then to sort a List, you can use Collections.sort.
I think this is you want to achieve
Save below code in file called "Snow.java" compile it and try to run it.
import java.util.ArrayList;
import java.util.Collections;
//As ".java" file can contain only single public java class
//I made Problem set class non-public so we can use its main method
//to run and see output
class ProblemSet {
public static void main(String[] args) {
Snow one = new Snow(1,1,1,1);
Snow two = new Snow(1,1,1,2);
Snow three = new Snow(1,1,1,3);
Snow four = new Snow(1,1,1,4);
Snow five = new Snow(1,1,1,5);
Snow six = new Snow(1,1,1,6);
ArrayList arrayList = new ArrayList();
arrayList.add(one);
arrayList.add(three);
arrayList.add(five);
arrayList.add(two);
arrayList.add(six);
arrayList.add(four);
System.out.println("Without sort");
System.out.println(arrayList);
sortSnow(arrayList);
System.out.println("With sort");
System.out.println(arrayList);
}
//this is your static method which takes argument as array list of Snow
//And it applies sorting logic based on compareTo method which you wrote
//in Snow class. As per java best practice Class name should start with
//Upper case letters and follow camel casing I renamed your class from
//"snow" to "Snow"
public static void sortSnow(ArrayList<Snow> input){
Collections.sort(input);
}
}
//This is you public class Snow
//If you want to keep it in separate java file put it
public class Snow implements Comparable<Snow> {
private int vast;
private int prior;
private int ethnic;
private int remarkable;
public Snow(int vast, int prior, int ethnic, int remarkable) {
this.vast = vast;
this.prior = prior;
this.ethnic = ethnic;
this.remarkable = remarkable;
}
public int getEthnic() {
return ethnic;
}
public void setEthnic(int ethnic) {
this.ethnic = ethnic;
}
public int getPrior() {
return prior;
}
public void setPrior(int prior) {
this.prior = prior;
}
public int getVast() {
return vast;
}
public void setVast(int vast) {
this.vast = vast;
}
public int getRemarkable() {
return remarkable;
}
public void setRemarkable(int remarkable) {
this.remarkable = remarkable;
}
public int compareTo(Snow compareSnow) {
// TODO Auto-generated method stub
int compareThese = ((Snow) compareSnow).getRemarkable();
//ascending order
return this.remarkable - compareThese;
}
//This is added because when you use array list to print
//it will print remarkable of particular Snow object
#Override
public String toString() {
return String.valueOf(remarkable);
}
}
I am trying to select a random method from the ones created inside the class. Is there a way to create an ArrayList and pass methods to it? I have attempted to do just that but I am getting an error when I try to add the method to the array.
public class Monkey{
private int energy;
String[] food = {"Meat", "Fish", "Bugs", "Grain"};
ArrayList<Activity> monkeyActivity = new ArrayList<>();
public Monkey(int energy) {
this.energy = energy;
}
public int getEnergy() {
System.out.println("Monkey energy level: " + energy);
return energy;
}
public void sound() {
System.out.println("Monkey: Oooo Oooo~!");
energy -= 3;
monkeyActivity.add(sound()); //I get an error message here when trying
//to add the method to the array
}
public void play(){
if (energy >= 8){
System.out.println("Monkey begins to play.");
energy -= 8;
}else {
System.out.println("Monkey does not have enough energy to play");
}
System.out.println("Energy remaining: " + energy);
}
public void eat(){
Random random = new Random();
int index = random.nextInt(food.length);
System.out.println("Monkey beings to eat " + food[index]);
energy += 5;
System.out.println("Energy remaining: " + energy);
}
public void sleep(){
System.out.println("Monkey is sleeping: Zzz...");
energy += 10;
System.out.println("Energy remaining: " + energy);
}
}
This is the separate class I have made for the generic Activity..
public class Activity {
private String sleep;
private String eat;
private String sound;
private String play;
public Activity(String sleep, String eat, String sound, String play) {
this.sleep = sleep;
this.eat = eat;
this.sound = sound;
this.play = play;
}
public String getSleep() {
return sleep;
}
public String getEat() {
return eat;
}
public String getSound() {
return sound;
}
public String getPlay() {
return play;
}
public void setSleep(String sleep) {
this.sleep = sleep;
}
public void setEat(String eat) {
this.eat = eat;
}
public void setSound(String sound) {
this.sound = sound;
}
public void setPlay(String play) {
this.play = play;
}
}
You are mixing up concepts.
technical issues:
return value clash
public void sound() {
// ...
monkeyActivity.add(sound());
The return value of your method sound() is void (which means no return value), but you try to add its (not existing) return value as element to the List. This is what your compiler complains about.
unintended recursion
public void sound() {
System.out.println("Monkey: Oooo Oooo~!");
energy -= 3;
monkeyActivity.add(sound());
In the last line you do a recursive call which means you call exactly the same method this code is in. If that happens unintended it almost ever results in a StackOverflowError.
writing classes without proper analysis
You have a class Activity.
But if you have a closer look this is not a single activity (as the classes name implies) but it is all possible activities.
As a result your collection monkeyActivity cannot hold single activities as elements.
Doing a wild guess I think what you wanted is more like this:
interface Activity{
void do();
}
public class Monkey{
private int energy;
String[] food = {"Meat", "Fish", "Bugs", "Grain"};
List<Activity> monkeyActivity = new ArrayList<>();
// ...
public void sound() {
monkeyActivity.add(new Activity(){
public void do(){
System.out.println("Monkey: Oooo Oooo~!");
energy -= 3;
}
});
}
You may store each method as Runnable, as any "action" is no-arg void method satisfying Runnable functional interface:
List<Runnable> actions = Arrays.asList(this::sound, this::play, this::eat, this::sleep);
to execute random method, just:
Random rnd = new Random();
actions.get(rnd.nextInt(actions.size())).run();
So I'm having this problem with adding an element to an ArrayList
I have a class Media with 3 fields and another class Mediatheque with 1 field(which is an ArrayList).
Let's say I have:
A Mediatheque media = new Mediatheque
An equals(Media m) method in class Media < (important method)
I need to write a method add(Media m) which:
If the media.contenu does contain an element equals to the Media m I want to add, I must NOT add it and increase the nbEx field of the element contained in media.contenu
-Else I can add it using the add method provided by the ArrayList ( This doesn't seem too hard)
So I tried to write a contains(Media) method which uses the equals(Media m) method I wrote for the Media class and then use the contains method in the add method.
My question is that how am I supposed to write the add method? < (The Question)
I must write this using ArrayList, it is a school assignment
Sorry about the long code and the bad English, I'm a complete noob.
Here is my Media class:
package Ex1;
public class Media {
private final String support; // Format: Book, CD, DVD,etc...
private final String titre; // Title
private int nbEx; // Number of copy
public Media(String titre, String support){
this.titre = titre;
this.support = support;
this.nbEx = 1;
}
public Media (){
titre = "";
support = "";
nbEx = 0;
}
public boolean equals(Media m){
boolean equality = false;
if (m instanceof Media){
equality = (this.titre.equals(m.titre) && this.support.equals(m.support));
}
return equality;
}
public Media(Media m){
this.titre = m.titre;
this.support = m.support;
}
}
And here is my Mediatheque class:
import java.util.ArrayList;
import static java.lang.System.out;
public class Mediatheque {
ArrayList<Media> contenu;
public Mediatheque(){
this.contenu = new ArrayList<Media>();
}
public Mediatheque(Mediatheque m){
this.contenu = m.contenu;
}
public boolean contains(Media m){
int i = 0;
boolean contain = this.contenu.get(i).equals(m);
for(i = 0; i<this.contenu.size(); i++){
if(contain)
break;
}
return contain;
}
public int indexOf(Media m){
boolean retVal = this.contenu.get(i).equals(m);
for(Media i : contenu){
if(contain)
break;
}
return i;
}
public void add(Media m){
if(this.contains(m)){
this.contenu.get(this.contenu.indexOf(m)).setNbEx(this.contenu.get(this.contenu.indexOf(m)).getNbEx()+m.getNbEx());
}else{
this.contenu.add(m);
}
}
My question is that how am I supposed to write the add method?
Sorry about the long code and the bad English, I'm a complete noob.
Thank you!
As stated by #NeplatnyUdaj in the comment of your question, the use of a Map would greatly improve your code. Instead of recording the number of medias inside the Media object, use a HashMap<Media, Integer> to store your data in this way:
new HashMap<Media, Integer> map = new HashMap<Media,Integer>();
if ( map.containsKey(key) ) {
map.put(key, (map.get(key) + 1));
} else {
map.put(key, 1);
}
Where key is the media. (m in your code)
When one overrides the equals() method, one is also supposed to override the hashCode() method. The equals() method takes an Object parameter. Here's how your Media class should look like:
// Media.java
public class Media
{
private final String support;
private final String title;
public Media(String title, String support)
{
this.title = title;
this.support = support;
}
public Media(Media media)
{
this(media.title, media.support);
}
#Override
public int hashCode()
{
return 31 * title.hashCode() + support.hashCode();
}
#Override
public boolean equals(Object object)
{
if (object instanceof Media)
{
Media media = (Media) object;
return media.title.equals(title) &&
media.support.equals(support);
}
return false;
}
}
Then use a HashMap to map the media with its number of copies. Here's how that's done:
// MediaMap.java
import java.util.HashMap;
import java.util.Map;
public class MediaMap
{
// Media to its Number of Copies mapping.
private Map<Media, Integer> mediaMap;
public MediaMap()
{
mediaMap = new HashMap<>();
}
public void add(Media media)
{
mediaMap.put(media, mediaMap.getOrDefault(media, 0) + 1);
}
public void removeOneMedia(Media media)
{
if (mediaMap.containsKey(media))
{
mediaMap.put(media, mediaMap.get(media) - 1);
}
}
// And so on...
}
Without overriding the hashCode() method in the Media class, the hash based collections won't work as expected.
You can also have a look at MultiSet data structure, and use that instead.
If you are to use ArrayList then here's how its done:
// Media.java
public class Media
{
private final String support;
private final String title;
private int numberOfCopies;
public Media(Media media)
{
this(media.title, media.support, media.numberOfCopies);
}
public Media(String title, String support, int numberOfCopies)
{
this.title = title;
this.support = support;
this.numberOfCopies = numberOfCopies;
}
#Override
public int hashCode()
{
return 31 * title.hashCode() + support.hashCode();
}
#Override
public boolean equals(Object object)
{
if (object instanceof Media)
{
Media media = (Media) object;
return media.title.equals(title) &&
media.support.equals(support);
}
return false;
}
public int getNumberOfCopies()
{
return numberOfCopies;
}
public void setNumberOfCopies(int numberOfCopies)
{
this.numberOfCopies = numberOfCopies;
}
}
And here's a MediaList class which uses ArrayList:
// MediaList.java
import java.util.ArrayList;
public class MediaList
{
private ArrayList<Media> mediaList;
public MediaList()
{
mediaList = new ArrayList<>();
}
public void add(Media media)
{
set(media, +1);
}
public void remove(Media media)
{
set(media, -1);
}
private void set(Media media, int change)
{
if (change == 0)
{
return;
}
int indexOfMedia = mediaList.indexOf(media);
if (indexOfMedia != -1)
{
Media m = mediaList.get(indexOfMedia);
m.setNumberOfCopies(m.getNumberOfCopies() + change);
if (change < 0 && m.getNumberOfCopies() <= 0)
{
mediaList.remove(media);
}
}
else if (change > 0)
{
mediaList.add(media);
}
}
// And so on...
}
I have refactored your classes a little bit. I also implemented an add method. I assumed that you want to add media to the mediatheque if it is not already in the list. If it is in the list you want to add the nbex to the nbex that the item in the list has, right?
As the others I would advise you to use a HashMap() for counting if you don't need the number for your media objects.
Media.class
public class Media {
private final String support; // Format: Book, CD, DVD,etc...
private final String titre; // Title
private int nbEx; // Number of copy
public Media(String titre, String support){
this.titre = titre;
this.support = support;
this.nbEx = 1;
}
public Media(Media m){
this(m.titre, m.support);
}
public Media (){
this("", "");
nbEx = 0;
}
public boolean equals(Media m){
if (m instanceof Media){
return (this.titre.equals(m.titre) && this.support.equals(m.support));
}
return false;
}
}
Mediatheque.class
public class Mediatheque {
ArrayList<Media> contenu;
public Mediatheque(){
this.contenu = new ArrayList<Media>();
}
public Mediatheque(Mediatheque m){
this.contenu = m.contenu;
}
public boolean contains(Media m){
for(Media media: this.contenu) {
if(media.equals(m) {
return true;
}
}
return false;
}
public int indexOf(Media m){
if(this.contenu.contains(m) {
return this.contenu.indexOf(m);
}
return -1;
}
public void add(Media m){
if(this.contains(m)) {
Media media = this.contenu.get(this.contenu.indexOf(m));
media.setNbex(media.getNbex() + m.getNbex());
} else {
this.contenu.add(m);
}
}
}
Hope this helps.
I am trying to practice with Polymorphism and using classes. I wrote a superclass called Card. I then wrote 3 subclasses called: IDCard, CallingCard, and DriverLicense. I then wrote another class called Billfold which is supposed to contain slots for two of the cards.
I am supposed to write a BillfoldTester program which adds two objects of different subclasses to a Billfold object.
In BillfoldTester, a DriverLicense object and a CallingCard object are instantiated and added to a Billfold, which refers to these objects with Card references.
I don't really understand how to do this. I created two Card objects but I am trying to add it to my Billfold and it wont work. I tried Billfold a = new Card (x); but it's not right... Any help is much appreciated.
public class BillfoldTester
{
public static void main (String[]args)
{
Card x= new IDCard("Julie", 1995);
Card j= new DriverLicense("Jess", 1997);
//Having trouble trying to put the objects into my Billfold and print it.
}
}
public class Billfold extends Card
{
private String card1;
private String card2;
void addCard(String Card)//Not sure if this should be String
{
card1=Card;
}
}
public class Card
{
private String name;
public Card()
//This is my superclass
{
name = "";
}
public Card(String n)
{
name = n;
}
public String getName()
{
return name;
}
public boolean isExpired()
{
return false;
}
public String format()
{
return "Card holder: " + name;
}
}
public class IDCard extends Card
{
//This is one of my subclasses
private int IDNumber;
public IDCard (String n, int id)
{
super(n);
this.IDNumber=id;
}
public String format()
{
return super.format() + IDNumber;
}
}
The polymorphism example. Not sure if the functionally is exactly what you need, but you can see the whole idea (I hope). See the showAllFormat() method of Billfold class.
The whole point is inside different format() methods of the DriverLicense and IDCard. Depending on the 'real' (or initially assigned) object the different method will be called even if you just only refer to 'Card' class.
NOTE:
You didn't provide your DriverLicense implementation, and my is just from head. I have a bit different constructor to show this sub-classes may be totally different.
import java.util.ArrayList;
import java.util.List;
class Billfold {
List<Card> list = new ArrayList<Card>(10);
void addCard(Card card) // Q: Not sure if this should be String
// A: You would like to add a Card
{
list.add(card);
}
void showAllFormat() {
// go polymorphism !...
// when you call this general 'format()' you see the subclasses
// 'format()' is executed, not from 'Card' class
for(Card x: list) {
System.out.println(x.format());
}
}
}
class Card {
private String name; /* owner */
public Card() //This is my superclass
{
name = "";
}
public Card(String n) {
name = n;
}
public String getName() {
return name;
}
public boolean isExpired() {
return false;
}
public String format() {
return "Card holder: " + name;
}
}
class IDCard extends Card {
//This is one of my subclasses
private int IDNumber;
public IDCard(String n, int id) {
super(n);
this.IDNumber = id;
}
public String format() {
return "(ID)" + super.format() + " " + IDNumber;
}
}
class DriverLicense extends Card {
private String type;
public DriverLicense(String n, String type) {
super(n);
this.type = type;
}
public String format() {
return "(DL)" + super.format() + " TYPE: " + type;
}
}
public class BillfoldTester {
public static void main(String[] args) {
Card x = new IDCard("Julie", 1995);
Card j = new DriverLicense("Jess", "AB");
Billfold bf = new Billfold();
bf.addCard(x);
bf.addCard(j);
bf.showAllFormat();
}
}
This is wrong. A Billfold is not a Card; it HAS Cards.
public class Billfold
{
List<Card> cards = new ArrayList<Card>();
void addCard(Card card) {
if (card != null) {
this.cards.add(card);
}
}
}
Prefer composition over inheritance.
You should have Billfold class have two Card objects, not two Strings:
public class Billfold
{
Card card1;
Card card2;
void addCard(Card card) {
if (card != null) {
if (card1 != null) {
this.card1 = card;
} else {
this.card2 = card;
}
}
}
Ok, you're largely on the right track, just a couple of things:
void addCard(String Card)//Not sure if this should be String
{
card1=Card;
}
You're right, this should be:
void addCard(Card card)
{
card1=card;
}
then to add them:
public class BillfoldTester
{
public static void main (String[]args)
{
Card x= new IDCard("Julie", 1995);
Card j= new DriverLicense("Jess", 1997);
Billfold bf = new Billfold();
Billfold.addCard(x);
Billfold.addCard(j);
}
}
Then add a method to Billfold to print the cards in it.
Edit: Oh yeah, and duffymo is totally right, you don't need to extends Card on Billfold
I'm doing an assignment for my computer science class.
I've done quite a bit of the assignment, but I'm having a little bit of trouble pulling the individual variables from the classes. We are just getting into classes and objects and this is our first assignment regarding them so I don't completely understand all of it. So far I've been able to print out the teams, but I haven't been able to pull the individual wins, losses, OTL and OTW so that I can compute whether or not each individual team is a winning team.
What I have done so far is create a class called winningRecord and getPoints, which returns a boolean deciding whether it's a winning team or not. (The formula for a winning team is if the points are > Games Played * 1.5 (as that is an even record).
I don't know how to pull the stats, as it has to be written in the HockeyTeam class. I have set it up so that the constructor sets the variables publicly so that the can be accessed, but as far as accessing them, I'm stumped.
As far as storing them once I am able to access them, would I just make a parallel method that has the points for each team, with just one digit assigned to each bin?
Here is all of the code, thanks for looking.

Thanks,

Sorry but I was only able to understand only a part of your question,from what I understood it seems you are not able to access individual wins, losses, OTL and OTW. I hope this answers your question if not please clarify a bit
To access OTL,OTW have a loop as below:
public class A1Q2fixed
{
public static void main(String[] parms) // main method
{
processHockeyTeams();
}
/*****************************/
public static void processHockeyTeams() // processing method
{
boolean[] winningRecord;
HockeyTeam[] hockeyTeams;
hockeyTeams = createTeams();
printTeams(hockeyTeams);
System.out.print("*********************\n");
printWinningTeams();
winningRecord = HockeyTeam.winningRecord(hockeyTeams);
for(HockeyTeam h:hockeyTeams)
{
System.out.println(h.losses);//To access and print losses
System.out.println(h.otw);//To access and print otw
System.out.println(h.otl);//To access and print otl
}
// printWinningTeams(hockeyTeams);
}
/*********************************/
public static void printTeams(HockeyTeam[] hockeyTeams)
{
for (int i = 0; i < hockeyTeams.length; i++)
{
System.out.println(hockeyTeams[i]);
}
}
public static void printWinningTeams()
{
}
public static HockeyTeam[] createTeams()
{
HockeyTeam[] teams;
HockeyTeam team;
int count;
teams = new HockeyTeam[HockeyTeams.getNumberTeams()];
team = HockeyTeams.getTeam();
for (count=0; (count<teams.length) && (team!=null); count++)
{
teams[count] = team;
team = HockeyTeams.getTeam();
}
return teams;
}
}
Also declare name as Static in HockeyTeam
