Java如何使用来自用户的布尔输入来结束do-while循环？

Question

所以我想让用户输入“真”或“假”来退出循环。正如我现在拥有的那样，无论我输入什么，它都会退出循环。

public static void main(String[] args) {
    // Color guard flags
    Scanner kb = new Scanner(System.in);
    Flag yourFlag;
    double weight;
    boolean correct;
    do {
        System.out.println("Hello!\nWhat colors are your silk? (most common two)\nHow long is your pole (in feet)?"
                + "\nWhat have you named your flag?\nHow heavy is your flag (in pounds)?");
        yourFlag = new Flag(kb.next(), kb.next(), kb.nextInt(), kb.next(), kb.nextDouble());
        if (yourFlag.getWeight() >= 7) {
            System.out.println("That sounds like a cool flag! It sounds pretty heavy though.");
        } else {
            System.out.println("That sounds like a cool flag!");
        }
        System.out.println("You've entered that your flag " + yourFlag.getName() + " is " + yourFlag.getWeight() + " pounds and "
                + yourFlag.lengthOfPole + " feet long. It also has the pretty colors " + yourFlag.silkColor1 + " and " + yourFlag.silkColor2);
        System.out.println("Is that correct? (True or flase)");
        correct = kb.nextBoolean();
    }
    while (correct = false);

顺便说一句，是的，这是一个关于颜色保护的程序

Answer 1

correct = false 是一个作业。

您应该使用!correct 来测试correct 是否为false。

示例代码；

do {
    //
}
while(!correct);
//while(correct == false)

如果你想要其他方式

do {
    //
}
while(correct);
//while(correct == true)
