如何在for-each循环中获取备用值？

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

Answer 1

您可以使用一些count变量，因为替代值在偶数或奇数索引中。

尝试此操作，甚至对于idexe

String [] yesBank = {"bdshfdhbck", "gsdhkcvdcjh", "fbdsjkfdsfj", "njjhsdfbjsfggsj"};
int count=0;
for(String arrayOFWord : yesBank)
{
    if((count++)%2 == 0)
        System.out.println(arrayOFWord);    
}

Answer 2

您可以尝试使用偶数索引：

String [] yesBank = {"bdshfdhbck", "gsdhkcvdcjh", "fbdsjkfdsfj", "njjhsdfbjsfggsj"};
        for(String arrayOFWord : yesBank)
        {
        if (Arrays.asList(yesBank).indexOf(arrayOFWord)%2  ==  0) System.out.println(arrayOFWord);    
        }
