线程“main”中的异常 java.lang.AssertionError。 我该怎么办？

问题描述

我正在尝试制作一个程序，该程序将从一系列数字中随机猜测并检查它是否与给定数字匹配。

它会运行 10 次，如果程序猜对了正确答案，那么它就会终止，但如果没有，它就会因拒绝而终止。

下面是我的代码 Guessing.java

public class Guessing {

    // Your local variables here
    private int low = 0;
    private int high = 1000;
    int randomNum;

    /**
     * Implement how your algorithm should make a guess here
     */
    public int guess() {
        randomNum = (int) ((Math.random() * (low - high)) + low);
        return randomNum;
    }

    /**
     * Implement how your algorithm should update its guess here
     */
    public void update(int answer) {
        if (answer == 1) {
            low = randomNum;
        } else if (answer == -1) {
            high = randomNum;
        }
    }
}
