in my recent uni work ive been given a task which i believe is to reassign values that have been set by getters and setters. The exact question is
" Edit the product’s main information that shares among all class such as ID,
Description, etc"
My attempt at this question is as followed.
public void editProductInformation() { //Standard level task 2 method 3
this.ID = 456890;
this.description = "Eggs";
this.recommendedUnitPrice = 10;
this.Unit = 6;
this.weight = 750;
}
}
this is also the code for the rest of the class
public class Product {
Scanner input = new Scanner(System.in);
protected int ID;
protected String description;
protected double recommendedUnitPrice;
protected double actualPrice;
protected int Unit = 1;
protected double weight;
protected LocalDate expiaryDate;
protected LocalDate expireDate;
public Product(int ID, String description, double recommendedUnitPrice, int unit, double weight, LocalDate expiarayDate) {
this.ID = ID;
this.description = description;
this.recommendedUnitPrice = recommendedUnitPrice;
this.Unit = unit;
this.weight = weight;
this.expiaryDate = expiarayDate;
}
public int getID() {
return this.ID;
}
public void setID(int ID) {
this.ID = ID;
}
public String getDescription() {
return this.description;
}
public void setDescripption(String description) {
this.description = description;
}
public double getRecommendedUnitPrice() {
return this.recommendedUnitPrice;
}
public void setRecommendedUnitPrice(double recommendedUnitPrice) {
this.recommendedUnitPrice = recommendedUnitPrice;
}
public int getUnit() {
return this.Unit;
}
public void setUnit(int unit) {
this.Unit = unit;
}
public double getWeight() {
return this.weight;
}
public void setWeight(double Weight) {
this.weight = Weight;
}
public LocalDate getExpiaryDate() {
return expiaryDate;
}
public void setExpiaryDate(LocalDate expiaryDate) {
this.expiaryDate = expiaryDate;
}
public void setPrice() {
System.out.println("Enter the price: ");
this.actualPrice = input.nextDouble();
}
public void setExpireDate() {
System.out.println("Enter the given date: ");
int day = input.nextInt();
int month = input.nextInt();
int year = input.nextInt();
LocalDate date = LocalDate.of(day, month, year);
this.expireDate = date;
}
public void comparePrice() { // Standard level task 2 method 1
if (recommendedUnitPrice == actualPrice) {
System.out.println("Price is equal");
} else if (recommendedUnitPrice < actualPrice) {
System.out.println("Price is less");
} else if (recommendedUnitPrice > actualPrice) {
System.out.println("Price is more");
}
}
public void verifyExpireProduct() { //Standard level task 2 method 2
if(expireDate == expiaryDate) {
System.out.println("Product is expired");
}
else System.out.println("Product is not expired");
}
I understand this question might not be explained well enough so i understand if people wish to downvote it. Any insight or help is much appreciated!
You can make an object of this class and then by using setter function defined in class you can set the value .
Product p1 = new Product();
p1.setId(5);
//This will set the Id to 5

I want to check duplicate IDs from a list with the data I inputted, then increment the qty variable in the list. If it's new data, it will add a new list.
This is my code
public void addBarang(Barang barang){
int id_barang = barang.getId();
if(this.list.isEmpty())
{
list.add(barang);
}
else
{
for(int i=0;i<list.size();i++)
{
if(list.get(i).getId() != id_barang)
{
list.add(barang);
System.out.println("Added");
break;
}
if(list.get(i).getId() == id_barang)
{
int new_qty = list.get(i).getQty()+barang.getQty();
list.get(i).setQty(new_qty);
}
}
}
}
Even if I input new data it always increments the qty of old data and the new data is not added (basically always end in the "else" section).
Code for inputing data
Gudang gudang1 = new Gudang(1,1);
System.out.println("ID: ");
int id = input.nextInt();
System.out.println("Jumlah: ");
int qty = input.nextInt();
System.out.println("Nama: ");
String name = input.next();
Barang barang = new Barang(id,name,qty);
gudang1.addBarang(barang);
Barang Class
public class Barang {
public static int id;
private String name;
private int qty;
public Barang(int id, String name, int qty) {
this.id = id;
this.name = name;
this.qty = qty;
}
public Barang(){
};
public int getId() {
return id;
}
public String getName() {
return name;
}
public int getQty() {
return qty;
}
public void setId(int id) {
this.id = id;
}
public void setName(String name) {
this.name = name;
}
public void setQty(int qty) {
this.qty = qty;
}
#Override
public String toString() {
return "Barang{" + "id=" + id + ", name=" + name + ", qty=" + qty + '}';
}
Gudang Class
public class Gudang {
public static int id;
private int location;
public List<Barang> list = new ArrayList<Barang>();
public Gudang(int id, int location) {
Gudang.id = id;
this.location = location;
}
public int getId() {
return id;
}
public int getLocation() {
return location;
}
public List<Barang> getList() {
return list;
}
public void setId(int id) {
this.id = id;
}
public void setLocation(int location) {
this.location = location;
}
public void setList(List<Barang> list) {
this.list = list;
}
public void addBarang(Barang barang){
int id_barang = barang.getId();
if(this.list.isEmpty())
{
list.add(barang);
}
else
{
for(int i=0;i<list.size();i++)
{
if(list.get(i).getId() != id_barang)
{
list.add(barang);
System.out.println("Added");
break;
}
if(list.get(i).getId() == id_barang)
{
int new_qty = list.get(i).getQty()+barang.getQty();
list.get(i).setQty(new_qty);
}
}
}
System.out.println("Size List = "+list.size());
}
public void duplicate(List<Barang> list2)
{
this.list.addAll(list2);
}
public void clearBarang(){
this.list.clear();
}
public void display(){
for(Barang barang: this.list){
System.out.println(barang);
}
}
IE : If I have id=1 and qty=1, then input a new data with id=2 and qty=2, the final result will end up with id=2 and qty=3. No new data int he list were added.
try using .equals to compare if the data exist in your list
Please check if ids are duplicate between your old and new data.
If you ids are unique then you can take advantage of Map and put id as key and barang object as value. Whenever you successfully lookup map increment quantity field of object.
At first guess i would change:
if(list.get(i).getId() != id_barang)
to:
if(list.get(i).getId() != barang.getId())
maybe id_barang is not the same as the id stored in the barang object.
I am making a text-based game on JavaFX, and after I hit a tree, I want to get Oak logs.
I have already built my inventory, and I have put default items in it such as Water, Bread, etc.
I am trying to add my Oak Logs to my inventory, but nothing is working.
Here is a part of my code:
Item ItemList[] = {new Bread(), new OakLog()};
Optional<ButtonType> result = alert.showAndWait();
if(result.get() == buttonTypeOak) {
woodcuttingXP = woodcuttingXP + oakXP;
dialogue.appendText("You swing at an Oak tree. + " + oakXP + "XP.\n");
dialogue.appendText("You gathered 1 log.\n");
mainCharacter.getInventory().add(new OakLog());
}
Here is my Item Class:
package game;
public class Item {
private String name;
private int weight;
private int quantity;
private int value;
private String description;
public Item(String name, int value, String description) {
this.name = name;
this.value = value;
this.description = description;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getWeight() {
return weight;
}
public void setWeight(int weight) {
this.weight = weight;
}
public int getQuantity() {
return quantity;
}
public void setQuantity(int quantity) {
this.quantity = quantity;
}
public int getValue() {
return value;
}
public void setValue(int value) {
this.value = value;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String toString() {
return getName();
}
}
And finally, here is my Character class:
package game;
import java.util.ArrayList;
import beverages.Water;
import items.OakLog;
import rawFood.Bread;
public class Character {
private String name;
private int hydrationLevel;
private int healthLevel;
private int hungerLevel;
private int woodcuttingLevel;
public int getWoodcuttingLevel() {
return woodcuttingLevel;
}
public void setWoodcuttingLevel(int woodcuttingLevel) {
this.woodcuttingLevel = woodcuttingLevel;
}
public int getHungerLevel() {
return hungerLevel;
}
public void setHungerLevel(int hungerLevel) {
this.hungerLevel = hungerLevel;
}
private ArrayList<Item> inventory = new ArrayList<Item>();
public ArrayList<Item> getInventory() {
return inventory;
}
public void setInventory(ArrayList<Item> inventory) {
this.inventory = inventory;
}
//creates a person with two basic items
public Character(String name){
this.name = name;
this.hydrationLevel = 100;
this.healthLevel = 100;
this.hungerLevel = 100;
this.woodcuttingLevel = 1;
addToInventory (new Bread());
addToInventory (new OakLog());
addToInventory (new Water());
}
//GETTERS AND SETTERS
public String getName() {
return name;
}
public int getHydrationLevel() {
return hydrationLevel;
}
public void setHydrationLevel(int hydrationLevel) {
this.hydrationLevel = hydrationLevel;
}
public int getHealthLevel() {
return healthLevel;
}
public void setHealthLevel(int healthLevel) {
this.healthLevel = healthLevel;
}
//END GETTERS AND SETTERS
/*Method Name: eat()
*Method Inputs: a piece of food
*Method Purpose: Will allow the user to eat food
*/
public Item getItemFromInventory(int index){
Item item = inventory.get(index);
return item;
}
public void addToInventory(Item item){
if(inventory.contains(item)){
item.setQuantity(item.getQuantity()+1);
}
else{
item.setQuantity(1);
inventory.add(item);
}
}
public String toString(){
return "Character Stats:\nName:" + getName() + "\nHydration: " + getHydrationLevel() + "\nHealth: " + getHealthLevel() + "\nWoodcutting: " + getWoodcuttingLevel();
}
}
In your code, you have:
if(inventory.contains(item)){
item.setQuantity(item.getQuantity()+1);
}
This just updates the quantity of the local variable item in the method, not the item in the inventory.
What would be the simplest method to print this array broken down into each mobile phone as a product number, name department etc, and then re print the same information sorted by product name. I have tried a couple different methods and am already passed the turn in date for the assignment but still need to figure it out for upcoming assignment this weekend. When I try to implement the comparator on MobilePhone class it forces me to make it abstract or use #override but I can't figure out where or what to override to make it work because the abstract class causes a multitude of other problems.
package InventoryPro2;
import java.util.*;
class MobilePhone {
private double productNumber; // Variables
private String name;
private String department;
private double unitsInStock;
private double unitPrice;
public MobilePhone() {
this(0.0, "", "", 0.0, 0.0);
}
public MobilePhone(double productNumber, String name, String department,
double unitsInStock, double unitPrice) { //assign variables
this.productNumber = productNumber;
this.name = name;
this.department = department;
this.unitsInStock = unitsInStock;
this.unitPrice = unitPrice;
}
public double getproductNumber() { // retrieve values

}
public String getname() {
return name;
}
public String getdepartment() {

}
public double getunitPrice() {

}

}
public void setproductNumber(double productNumber) {
this.productNumber = productNumber;

}
}
public class InventoryPro2 {

public static void main(String args[]) {
System.out.println("Mobile Phone Inventory Program");

System.out.println("Order of inventory before sorting:");
System.out.println();
}
}
(Also, what is the best way to take just one piece of information out of each part of the array such as the totalInv and total all of those numbers to print?) Do I have unnecessary code here or have I done everything right thus far? I have to say that learning this coding language in an online format has not been a very enjoyable experience thus far..
Here is how to sort by name
import java.util.Arrays;
import java.util.Comparator;

System.out.println();// skips a line

}
});
System.out.println("Order of inventory after sorting by name:");
System.out.println(Arrays.toString(phones));
}
}
class MobilePhone {
private double productNumber; // Variables
private String name;
private String department;
private double unitsInStock;
private double unitPrice;
public MobilePhone() {
this(0.0, "", "", 0.0, 0.0);
}

public void setname(String name) {

}
public void setunitPrice(double unitPrice) {

#Override
public String toString() {
return "MobilePhone [productNumber=" + productNumber + ", name=" + name
+ ", department=" + department + ", unitsInStock="
+ unitsInStock + ", unitPrice=" + unitPrice + "]";
}
}
1 - To print content of MobilePhone class: Override default toString method like this:
#Override
public String toString() {
return "MobilePhone [productNumber=" + productNumber +
", name=" + name + ']'; // add more info if needed
}
2 - To allow sorting by name: Have MobilePhone class implement Comparable interface like
this:
class MobilePhone implements Comparable {
...
#Override
public int compareTo(Object o) {
MobilePhone m = (MobilePhone) o;
return (this.name.compareTo(o.name));
}
}
EDIT: To print your array of MobilePhone object you can do:
System.out.printf("Phones: %s%n", Arrays.toString(phones));
The compiler gives me an error message saying it can't find movies[x].getTitle() and movies[x].getYear. I've been wondering if it's a problem with going through the interface to get to the classes
Here is the error:
MathewBorumP5.java:68: error: cannot find symbol

And finally my interface.
public interface Profitable {

public abstract double calcRevenue();
public abstract double calcProfit(double revenue);
}
The Profitable interface doesn't have the methods that you're trying to call, and so the compiler is correct to complain about this to you. The array variable doesn't know what type of object each array item might hold, and in fact one could hold one type of item only to have it changed later, so it makes sense for the compiler to behave this way. A kludge would be to test each item held by the array to see what type it actually is, say by using instanceof, but this is a very fragile solution and is not recommended. Safest is to only call Profitable methods on Profitable array items and to try to use the magic of polymorphism to allow each object to do different behaviors for the same method call.
Note that if all of the items held by the array will always be Movie or Movie child items, then by all means use an array of Movie rather than an array of Profitable.
You are correct, the issue is with your Profitable interface.
When you create the array item(Profitable[] movies), this means that only the methods defined in this interface will be available to you.
An array of Movie objects is probably what you are after here. All of those objects appear extend Movie and implement Profitable, so you will able to access everything this way.
Okay my assignment is to read in from 2 separate files. The first file reads in "HallOfFameMember" and should then be stored in a vector.
The second should read in and then be stored to an array of HallOfFame
The HallOfFameMember object has 10 fields. In order firstName, lastName, deceased, month born, day born, year born, totalEarned, yearsPlayed, yearInducted, hall of fame id
The day/month/year born are all going to a separate class to create a date born. The date born is then set within HallOfFameMember. The Fields for a record will be separated by varying numbers of spaces and/or tabs (whitespaces).
After reading a record from this file, call the 10-arg constructor of HallOfFameMember, using the fields from the record as arguments in the constructor call. Add this new HallOfFameMember object to tempHallOfFameMemberVec.
The HallOfFame object has 5 fields. In order hallOfFameId, city, costToVisit, numberOfVisitorsPerYear, and name.
After reading a record from this file, call the 5-arg constructor of class HallOfFame, using the arguments obtained from the line in the file. Add this new HallOfFame object to tempHallOfFameArr.
This is all to be done from the command line.
I know that my current code will not work, I was just trying to figure out some way to do this. Vectors are completely new to me, along with BufferedReader, and I've been trying to use the examples on javapractice.com as well as a few other sites for reference. I know it will be something small that I am overlooking/missing and Ill have a duh moment when I figure it out.
At any rate my current question is this.
How do I read in from a file that has "any number of white spaces/tabs" as the delimiter. And then parse that into the appropriate fields within the appropriate class?
Giving me the code isn't gonna help, if you could just point me to a website or link that I can read to have my duh moment that would be great.

A couple tips:
I don't want to do your homework for you, but I can't think of a quick tutorial to point you to that covers exactly what you're doing.
You're on the right track with .split, but your delimiter expression won't work for multiple spaces/tabs. Try this:
String delims = "\\s+";
That will break up your string on any consecutive sequence of one or more whitespace characters.
Also, you need to move the split up into your while loop, as well as the creation of each HallOfFameMember object. In each iteration of the loop you want to:
Split the line that you read from the file to create an array of strings representing the values for one record.
Create a new HallOfFameMember using the values from your string array. (tempHallOfFameArr[0] for first name, tempHallOfFameArr[1] for last name, etc.)
Add the new HallOfFameMember that you created to your vector
If you'd like more detail on any of these steps, I'm happy to elaborate.
