如何在Java中迭代字符串？ [英] How can I iterate over a string in Java?

问题描述

public static Boolean cmprStr( String s1, String s2 )
{
    // STUFF
}

我想迭代s1以确保s1中的每个字符都包含在s2中。

I want to iterate through s1 to make sure that every character in s1 is included in s2.

推荐答案

public static Boolean cmprStr( String s1, String s2 )
{
    for (int i = s1.length() - 1; i >= 0; --i) {
         if (s2.indexOf(s1.charAt(i)) == -1) {
             return Boolean.FALSE;
         }
    }
    return Boolean.TRUE;
}
