如何在 for-each 循环中获取替代值？

String [] yesBank = {"bdshfdhbck", "gsdhkcvdcjh", "fbdsjkfdsfj", "njjhsdfbjsfggsj"};
for(String arrayOFWord : yesBank)
{
    System.out.println(arrayOFWord);
}

Answer 1

您可以简单地使用一个标志；

    String [] yesBank = {"bdshfdhbck", "gsdhkcvdcjh", "fbdsjkfdsfj", "njjhsdfbjsfggsj"};
    boolean flag = true;
    for(String arrayOFWord : yesBank)
    {
        if (flag)
        {
            System.out.println(arrayOFWord);
        }
        flag = !flag;
    }

这适用于奇数元素。对于偶数元素，以 flag = false 开头。
