The reason your questions are not outputting is simple.
public void pickOperation(){
int operation = 0;
System.out.println("1 - Addition\n2 - Subtraction\n3 - Multiplication\n4 - Division ");
operation = input.nextInt();
}
You are creating a local variable, operation, and assigning the input value to it. This means that the field, operation, is never set, so when it comes to the switch statement in your getProblem method, it doesn't output anything because it doesn't match the switch statement.
To fix this, simply remove the int operation = 0; declaration.
Edit
Just noticed the same problem with your pickDifficulty method. I would strongly recommend you have a look at this tutorial on scope in Java.
Explanation of your Problem
Okay. So let's look at your code:
public void pickOperation(){
int operation = 0;
// Declare an int, called 'operation'.
System.out.println("1 - Addition\n2 - Subtraction\n3 - Multiplication\n4 - Division ");
// Set the newly declared value to an int from the keyboard.
operation = input.nextInt();
}
As soon as this method is finished, the value inside operation is destroyed. The reason why it isn't staying in your field int operation, is because you declared a more local operation variable. By removing the int operation = 0; at the start of this method, you force the JVM to look for the next available variable named operation in your class, which is in the field. That's why, when you remove the first assertion statement, your value for operation will stick around.

the problem is : int operation = 0; you need to take the value of the operation in operation variable which you create it in Main
Try this :
import java.util.Random;
import java.util.*;
import java.util.Scanner;
import javax.swing.JOptionPane;

If the intent is to display questions in a random order only once, then what you could do is shuffle the indexes to be presented in a queue structure.
The following method creates a list of the indexes from 0 to count - 1, shuffles them and returns a Queue that when poll() is called will return the next index to offer up. Keep calling this until null is returned for no more questions.
import java.util.ArrayDeque;
import java.util.Collections;
import java.util.List;
import java.util.stream.IntStream;
import static java.util.stream.Collectors.toList;
private Queue<Integer> questionOrder(int count) {
List<Integer> indexes = IntStream.range(0, count)
.mapToObj(n -> n)
.sorted()
.collect(toList());
Collections.shuffle(indexes);
return new ArrayDeque<>(indexes);
}
You could then use this as:
private void askQuestions(String[] questions) {
Queue<Integer> order = questionOrder(questions.length);
System.out.println(order);
Integer index;
while ((index = order.poll()) != null) {
String question = questions[index];
System.out.println(question);
// do your presentation logic.
}
}

I've got an assignment that requires me to have the user guess a random color generated by the program, then display the total results. My code works fine, but I'm wanting to break it down into another method. Specifically, the section that receives input from the user. I want that in its own method, then the main method only displaying results. I tried creating a new object for the user's color choice, but that didn't work. I'm not sure what to do next. Thank you for your time!
import java.util.Scanner;
import java.util.Random;
public class ESP
{
public static void main(String[] args)
{
String colorChoice;
int correct = 0, incorrect = 0;
Scanner keyboard = new Scanner(System.in);
for(int i = 1; i <= 10; i++)
{
System.out.print("Choose either red, green, blue, orange or yellow! ");
colorChoice = keyboard.nextLine();
System.out.println("You chose: " + colorChoice);
String computerChoice = computerColorChoice();
System.out.println("The computer chose: " + computerChoice);
if(colorChoice.equalsIgnoreCase(computerChoice))
{
correct++;
}
else
{
incorrect++;
}
}
System.out.println("Amount of times you guessed correctly: " + correct);
System.out.println("Amount of times you guess incorrectly: " + incorrect);
}
public static String computerColorChoice()
{
String randomColor;
int randomNumber;
Random random = new Random();
randomNumber = random.nextInt(4);
switch (randomNumber)
{
case 0:
randomColor = "Red";
break;
case 1:
randomColor = "Green";
break;
case 2:
randomColor = "Blue";
break;
case 3:
randomColor = "Orange";
break;
case 4:
randomColor = "Yellow";
break;
default:
randomColor = " ";
}
return randomColor;
}
}

You can add a method for the user choice:
public static String userColorChoice()
{
Scanner keyboard = new Scanner(System.in);
System.out.print("Choose either red, green, blue, orange or yellow! ");
String userColorChoice = keyboard.nextLine();
System.out.println("You chose: " + userColorChoice);
return userColorChoice;
}
Also you can update your computerColorChoice as follows:
public static String computerColorChoice()
{
String randomColor;
int randomNumber;
Random random = new Random();
randomNumber = random.nextInt(4);
switch (randomNumber)
{
case 0:
randomColor = "Red";
break;
case 1:
randomColor = "Green";
break;
case 2:
randomColor = "Blue";
break;
case 3:
randomColor = "Orange";
break;
case 4:
randomColor = "Yellow";
break;
default:
randomColor = " ";
}
System.out.println("The computer chose: " + randomColor);
return randomColor;
}
And finally update your main:
public static void main(String[] args)
{
int correct = 0, incorrect = 0;
for(int i = 1; i <= 10; i++)
{
if(userColorChoice().equalsIgnoreCase(computerColorChoice()))
correct++;
else
incorrect++;
}
System.out.println("Amount of times you guessed correctly: " + correct);
System.out.println("Amount of times you guess incorrectly: " + incorrect);
}
I hope this help you.

The program ask for a month and it could be a string or int. In the isDigitsOrSpecial method, it works and it has the same format in my method isString. The difference is that when I want to enter the month in a string way (ex.january), it will ask me twice. So, I don't know what to do. I tried a lot of ways but it doesn't work. Do you have any suggestions?
Here's my full code. You can try to run it, and see the problem where you have to input twice the name of the month in a string way.
I would really appreciate any of your suggestions.

I am trying to make a text based game. I am putting somethings I have learned to practice.
When you read about my problem you will probably be confused. My problem contains methods that have yet not been explained in what they do. This is so it does not get too confusing. Each piece of code will have a description of what methods it has and what they do.
My problem: I have a class named CharStartingPoint, this class is the main starting point to my game. Inside the class I call the choose(); method which is a method from class CharObe then the settingNPC(); and bbs(); methods are called, both of those methods are from CharWosna class. The bbs(); method just returns a boolean referenced, player1HasShieldBo, and prints out string player1HasShield. (player1HasShield and player1HasShieldBo are from class CharObe and player2HasShieldBo is from class CharWosna). When choose(); is called, and the player types yes to the question "Do you have a shield?", if the if statement sees if the user typed yes it will call a method named setPlayerShieldTrue(boolean HasSield); and pass player1HasShieldBo which sets player1HasShieldBo = true. If I type System.out.println(player1.player1HasShieldBo); and
System.out.println(player1.player1HasShield); from class CharStartingPoint, it prints out true and yes. Class CharStartingPoint has no problem accessing CharObe's variables. When CharWosna class tries accessing CharObe's variable, CharWosna can access them but they are not initialized, WHY????? for this problem to be seen, when method settingNPC(); is called, player2HasShieldBo is set to true if player2HasShieldBo is true. In this case player2HasShieldBo is set to false because class CharWosna accessed player1HasShieldBo from class CharObe, but it is not initialized although it had been initialized earlier. String player1HasShield prints out null when accessed from class CharWosna. WHY????
player1 is of type CharObe and has a constructor of CharObe.
player2 is of type CharWosna and has a constructor of CharWosna.
Here is my code by chunks and explained
Class CharObe:
The choose(); method: The choose method asks the user if they have a shield or not. If the user types no to the question, do you have a shield? the boolean player1HasShieldBo is set to false. If the user types yes, then inside the if statement the setPlayerShieldTrue(); method is called.
The setPlayerShieldTrue(boolean HasSield); method: this method takes in a boolean. Inside this boolean the local variable HasSield is set to true which then is assigned to player1HasShieldBo.
The returnIfHasShield(); method: this method just returns boolean player1HasShieldBo
import java.util.Scanner;
public class CharObe implements CharInterface {
String player1HasShield;
boolean player1HasShieldBo = false;
int player1ShieldLevel;
int player1ShieldHealth;
boolean valid = false;
Scanner keyBoard = new Scanner(System.in);
public void choose(){
do{
//asking the user if they have a shield or not
System.out.println("\ndo you have a shield? (if yes only type" +
"'yes' if no type 'no')");
System.out.print("Shield? yes or no? > ");
if(keyBoard.hasNext()){
player1HasShield = keyBoard.next();
if(player1HasShield.equalsIgnoreCase("yes")){
System.out.println("You have a SHIELD!!!");
setPlayerShieldTrue(player1HasShieldBo);
System.out.println("What is your shield Level? (Only" +
"numbers 1-5)");
do{
System.out.print("Shield level > ");
if(keyBoard.hasNextInt()){
player1ShieldLevel = keyBoard.nextInt();
if(player1ShieldLevel >= 1 && player1ShieldLevel <= 5){
valid = false;
}else{
System.out.println("PLEASE only numbers from 1-" +
" 5");
valid = true;
}
}else{
System.out.println("Only numbers are valid");
keyBoard.next();
valid = true;
}
}while(valid);
}else{
System.out.println("You did not type 'yes'"
+ " now you dont have a shield...");
player1ShieldLevel = 0;
valid = false;
}
}
}while(valid);
if(player1HasShieldBo){
switch(player1ShieldLevel){
case 1: player1ShieldHealth = 5; break;
case 2: player1ShieldHealth = 7; break;
case 3: player1ShieldHealth = 15; break;
case 4: player1ShieldHealth = 20; break;
case 5: player1ShieldHealth = 30; break;
}
}else{
player1ShieldHealth = 0;
}
if(player1HasShieldBo){
System.out.println(
"\nPlayer1's shield level: "+ player1ShieldLevel +
"\nplayer1's shield HP: " + player1ShieldHealth);
}else{
System.out.println(
"\nPlayer1's shield level: "+ player1ShieldLevel +
"\nplayer1's damage: " + player1Damage);
}
System.out.println("\nSetting player2's variables...");
}
public void setPlayerShieldTrue(boolean HasSield){
HasSield = true;
player1HasShieldBo = HasSield;
}
public boolean returnIfHasShield(){
return player1HasShieldBo;
}
}
Method settingNPC();, this method sets boolean player2HasShieldBo = true if what is returned from method returnIfHasShield(); is true. If what is returned is not true then player2HasShield will not be initialized and will stay false. That is the problem, although what is returned from returnIfHasShield(); is player1HasShieldBo equaled to true, it will always returns false when access by CharWosna class.
Method bbs();, this method prints out player1HasShieldBo and player1HasShield which come out to false and null because they are not initialized altough they had been earlier, why does this happen?
import java.util.Random;
public class CharWosna implements CharInterface{
//player2 variables
boolean player2HasShieldBo = true;
int player2ShieldLevel;
int player2ShieldHealth;
CharObe toGet = new CharObe();
public void settingNPC(){
if(toGet.returnIfHasShield()){
player2HasShieldBo = true;
player2ShieldLevel = toGet.player1ShieldLevel;
player2ShieldHealth = toGet.player1ShieldHealth;
System.out.println("Wosna's shield level: " + player2ShieldLevel +
"\nWosna's shield health: " + player2ShieldHealth
);
}else{
player2ShieldHealth = 0;
System.out.println("To have a fair fight, Wosna, like you, will"
+ "not have a shield.");
}
}
public void bbs(){
System.out.println(toGet.player1HasShieldBo + " " +
toGet.player1HasShield);
}
}
Class CharStarting point, this class calls all methods
I found out the reason that CharObe's variable are initialized and can be accessed nicely in this class, it's because this class calls the choose(); method.
public class CharStartingPoint {
public static void main(String[] args) {
System.out.println("Welcome! Fellow traveler.");
System.out.println("please input proper information in order to"
+ procceed to fight.\n");
CharObe player1 = new CharObe();
CharWosna player2 = new CharWosna();
player1.choose();
player2.settingNPC();
player2.bbs();
System.out.println(player1.player1HasShieldBo);
System.out.println(player1.player1HasShield);
}
}
Interface CharInterface, this is not yet used.
public interface CharInterface {
int hurt(int curHealth, int hurting);
int damage(int hitDamage);
int shield(int shieldHealth, int shielLevel);
}
*Another problem is when i create an object in class CharObe, it straight up gives me a java.lang.StackOverflowError, why is that. *
I dont know why I have all these problems. I may just have somethings that are very simple that have been messing up my program, I dont know.
Things I have tried
-directly accessing the boolean player1HasShieldBo from class CharWosna
-creating another boolean having it have the value of player1HasShieldBo(when player1HasShieldBo equaled to true)
-initializing player1HasShieldBo from class CharObe (did not turn out as wanted, it always equaled true)
if you want to see all my code here it is.

Thank you

First thing, Your code will work for setting the boolean. But you have some mistakes.
The stackOverflow is caused since you create a object of CharObe within the same class as a attribute. So for creating a CharObe object it needs to create a CharObe and so on...
the culprit line: on CharObe class
CharObe f = new CharObe();//remove this
Second thing, you cant just create an object of CharObe in CharWosna just to read the attributes.
This code is culprit too:
//CharObe object created for acquiring CharObe's variables in that class
CharObe toGet = new CharObe();
Instead try passing the player1 object when creating player2 in the constructor.
like this in CharWonsa:
//CharObe object created for acquiring CharObe's variables in that class
CharObe toGet;
public CharWosna(CharObe obe) {
toGet=obe;
}
And finally in the class CharStartingPoint, create objects like this:
CharObe player1 = new CharObe();
CharWosna player2 = new CharWosna(player1);
Another better way is that you maintain a GameContext class seperately and have all the necessary data like players there, and access from there.
You're welcome. Next time be precise with what you ask.

I have got it working so that it keeps count of the games won and lost, as well as assigning a score based on the amount of attempts/lives saved but I haven't been able to find a way to get it to keep a total score for all of the games played. Each game unfortunately has a seperate score. If anyone can advise me on a way of doing this, it would be greatly appreciated.

Create an int totalScore variable where winCounter, loseCounter and score are defined. Then increment it after each call to scoreGame()
score = scoreGame(attempts);
totalScore += score;
System.out.println("Your score is: " + score);
If you want to permanently save statistics between sessions then it's a whole nother story. You would need to write your scores to a file after each round and then start your program by reading this score file. It's hardly impossible, but requires a bit more code.
