Need help ending number guessing game and asking if user wants to play again

[willis lee]

This is a number guessing game that allows 2-5 players. There is a random number generated for each player. I want the game to end as soon as the 1st player guesses the number correctly and ask for user input if they want to play again. Previously I was able to get the game to end after the 1st player to guess correctly by using system.exit but now I want to have the option for players to choose to play again and I was hoping someone can help me.

Here is my code:

import java.util.*;

public class random_number {


public static void main(String[] args) {

boolean runAgain = true;
Scanner in = new Scanner(System.in);

int [] random ;
random = new int[6];

boolean [] won ;
won = new boolean [6];

int counter=0;
boolean stopPlay = false;

System.out.println ("How Many players are there?");
int player = in.nextInt();

for (int x = 1; x<= player; x++){
random[x] = getNumber();
}

while(!stopPlay){
counter++;
int[] guesses = new int[player];
//create array to store guesses
System.out.println("Guess a number between 1 and 100");
for(int i=1; i<=player; i++){
guesses[i-1]= getGuess(i);
}
for(int i=1; i<=player; i++){
System.out.print("Player " + i + ", your guess is ");
won[i]= compare(guesses[i-1], random[i], counter);
if (won[i] == true){
break;
}
}

}
System.out.println ("Play again: (y/n)");
String playAgain = in.nextLine();
if (playAgain.equals('y')){
runAgain = true;
}
else {
System.exit(0);
}
// remember to to ask how:
// if won[1] = true how do you set stopPlay to true then also
//is this where it goes?

}


public static int getNumber (){ // creates method getNumber
Random generator = new Random(); // creates the generator to allow a random number to be generated
int a = generator.nextInt(100)+1;
return a;
}
// this is first method
public static int getGuess(int i){

Scanner in = new Scanner(System.in);
System.out.print("Player " + i + ": ");
int guess = in.nextInt();
return guess;
}
// this is second method
public static boolean compare(int guess, int random, int count){

if(guess < random){
System.out.println("Too Low");
}
if(guess > random){
System.out.println("Too High");
}
if (guess == random){
System.out.println("Correct!");
System.out.println("The number of guesses: " + count);
System.out.println("You Win!");


return true;
}
else return false;
}
//this is third method
}

Thanks.

Hello willis, and welcome to the Ranch!

but now I want to have the option for players to choose to play again

Whenever you say that you want a part of a program to repeat, you should automatically think of using a loop of some kind and in fact enclosing the code that needs to repeat in this loop. In this situation where you don't know initially how many times the loop will occur, but you do know that it will occur at least one time, you should consider using a do-while loop.

Here is my code:

Your code is all left-justified and hard to read. As your goal is to get as many people as possible to read your code, you'll probably want to make it easier to read by editing this code so that it is properly indented.

Best of luck and again, welcome!

OK I really don't have any idea what I am doing but this is what I came up with so far. Sorry my indenting is terrible, I'm not sure how to indent correctly.

All I wish to know now is how I can get this program to stop asking for guesses after the first person guesses correctly. I tried the break command but there were errors and again, I don't have much experience. I want the program to ask if the user wants to play again after the first player guesses their number correctly.

import java.util.*;

public class random_number {

    public static void main(String[] args) {

        boolean play = true;
        String answer = "y";
        String playAgain;
        Scanner in = new Scanner(System.in);
        int y = 1;
        
    while (true){

        int [] random ;
        random = new int[6];

        boolean [] won ;
        won = new boolean [6];

        int counter=0;
        boolean stopPlay = false;

        System.out.println ("How Many players are there?");
        int player = in.nextInt();

        for (int x = 1; x<= player; x++){
            random[x] = getNumber();
}

    while(!stopPlay){
        counter++;
        int[] guesses = new int[player];
//create array to store guesses
        System.out.println("Guess a number between 1 and 100");
        for(int i=1; i<=player; i++){
            guesses[i-1]= getGuess(i);

        for(int i=1; i<=player; i++){
            System.out.print("Player " + i + ", your guess is ");
            won[i]= compare(guesses[i-1], random[i], counter);
            if (won[i] == true){
            break;
}
}

}
    System.out.println ("Play again: (y/n)");
    answer = in.nextLine();
    while (play==true);
    if (answer=="yes" || answer == "y"){
        play = true;
        
    } else if (answer == "no" || answer == "n"){

    }
    
    }

    public static boolean compare(int guess, int random, int count){
        
        
        if(guess < random){
            System.out.println("Too Low");
}
        if(guess > random){
            System.out.println("Too High");
}
        if (guess == random){
            System.out.println("Correct!");
            System.out.println("The number of guesses: " + count);
            
            System.out.println("You Win!");            

        return true;
