java - 用java(数组)猜用户想过的数字

Question

我是编程新手，我们的老师要求我们编写一个程序，该程序可以使用数组猜测用户所想的数字。我这样做了:

import java.util.Scanner;

public class Exercise11 {

    public static void main(String[] args) {
        Scanner entrada = new Scanner(System.in);
        System.out.println("Think a number between 1 and 100");
        int array[] = new int[100];

        for (int x = 0; x < 100; x++) {
            array[x] = (int) ((Math.random() * 100) + 1);
        }
        //This allow us to fill the array with random numbers, without caring if they are repeated or not.
        for (int i = 0; i < 100; i++) {
            for (int j = 0; i < 100; j++) {
                while (true) {
                    if (i != j && array[i] == array[j]) {
                        array[j] = (int) ((Math.random() * 100) + 1);
                    } else
                        break;
                }
                //If a number is repeated, this will swap that number with another number.
            }
        }

        //Now we have filled the array. We ask the user:
        for (int y = 0; y < 100; y++) {
            System.out.println("¿Is it your number " + array[y] + "?");
            String respuesta = entrada.next();
            switch (respuesta) {
                case "Yes":
                    System.out.println("I knew it! I only needed " + y + " trys!");
                    break;
                case "No":
                    break;
            }
        }
    }
}

但是当我执行它时它仍然抛出错误，像这样:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 100
    at Ejercicio11.main(Ejercicio11.java:25).

我已尝试调试它，但我仍在学习如何调试，但找不到错误。有人可以帮我确定错误在哪里以及如何解决吗？非常感谢!

你的内部 for 循环的条件应该是

for (int j = 0; j < 100; j++){

(条件是j < 100，不是i < 100)
