    Default Mastermind game

    I am confused on how to write a Boolean that will end the game if the guess is correct if anyone can help I would greatly appreciate it
    My teacher calls it baseball lol so I made a baseball class which contains all of my methods and arraylist of words to guess from
    <import java.util.*;
    import java.io.*;
     
    public class Baseball {
     
        private ArrayList<String> numbers;
        private String secret;
        private int count, strike, ball;
        private StringBuffer hideNumber = new StringBuffer();
        private StringBuffer disguise = new StringBuffer();
     
        public Baseball(){
     
            numbers = new ArrayList<String>();
            numbers.add("012");
            numbers.add("123");
            numbers.add("456");
            numbers.add("789");
            numbers.add("098");
            numbers.add("765");
            numbers.add("432");
            numbers.add("109");
            numbers.add("876");
            numbers.add("543");
            numbers.add("210");
            numbers.add("987");
            numbers.add("654");
            numbers.add("321");
            numbers.add("135");
            numbers.add("579");

    how to write a Boolean that will end the game
    A boolean variable can have two values: true and false.

    You can use an if statement to test its value and do something that will "end the game" if it is true.

    Define the boolean as a class variable.
    Set it true when you want other parts of the class to know about it.
    Test its value when you want to exit the game if true.
    If you don't understand my answer, don't ignore it, ask a question.

    What are all those numbers for?

    numbers = new ArrayList<String>();
            numbers.add("012");

    the numbers were for creating my own arraylist that contained a bank of number strings for the computer to randomly generate one as the secret number to have the user guess from
