如何检查布尔数组中的所有元素都为真 [英] How to check ALL elements of a boolean array are true

问题描述

我有一个布尔数组的大小取决于在随机选择的字符串的大小。

I have a boolean array whose size depends on the size of a randomly selected string.

所以我有这样的事情：

boolean[] foundLetterArray = new boolean[selectedWord.length()];

随着程序的进行，这个特定的布尔数组被填充有真值的数组中的每个元素。我只是想尽快数组中的所有元素都是真打印的声明。所以，我曾尝试：

As the program progresses, this particular boolean array gets filled with true values for each element in the array. I just want to print a statement as soon as all the elements of the array are true. So I have tried:

if(foundLetterArray[selectedWord.length()]==true){
    System.out.println("You have reached the end");
}

这给了我一个出界异常错误的。我也曾尝试包含（）方式，但最终即使数组中的1个元素是真正的循环。我需要一个for循环，通过阵列中的所有元素迭代？如何设置一个测试条件是什么？

This gives me an out of bounds exception error. I have also tried contains() method but that ends the loop even if 1 element in the array is true. Do I need a for loop that iterates through all the elements of the array? How can I set a test condition in that?

推荐答案

使用的增强的for循环，您可以轻松地遍历数组，不需要索引和大小计算：

Using the enhanced for loop, you can easily iterate over an array, no need for indexes and size calculations:

private static boolean allTrue (boolean[] values) {
    for (boolean value : values) {
        if (!value)
            return false;
    }
    return true;
}
