如何打印isdogcolorRed数组值为true对应的dogNames数组元素

我们可以通过遍历两个数组的索引，定位isdogcolorRed中值为true的位置，再取出对应索引的dogNames元素即可。以下是几种常见编程语言的实现示例：

JavaScript #

const dogNames = ['Charlie', 'Luis', 'Annie'];
const isdogcolorRed = [true, false, false];

for (let i = 0; i < isdogcolorRed.length; i++) {
  if (isdogcolorRed[i]) {
    console.log(dogNames[i]);
  }
}

Python #

dog_names = ['Charlie', 'Luis', 'Annie']
is_dog_color_red = [True, False, False]

for name, is_red in zip(dog_names, is_dog_color_red):
    if is_red:
        print(name)

Java #

public class Main {
    public static void main(String[] args) {
        String[] dogNames = {"Charlie", "Luis", "Annie"};
        boolean[] isdogcolorRed = {true, false, false};
        
        for (int i = 0; i < isdogcolorRed.length; i++) {
            if (isdogcolorRed[i]) {
                System.out.println(dogNames[i]);
            }
        }
    }
}
