如何比较包含相同字符的2个字符串 [英] How to compare 2 strings containing same characters

问题描述

我的问题是，我有2个字符串，比如String1& String2的。现在我想检查这两个字符串是否包含相同的字符，不管它们的顺序如何。

My question is that, I have 2 strings, say String1 & String2. Now I want to check whether these 2 strings contain same characters or not, irrespective of their sequence.

假设 String1 =qwerty， String2 =qywter。现在这些字符串包含相同的字符但序列不同。那么有没有可用于显示这些字符串包含相同字符的函数？ Can equals（）方法可以吗？

Suppose String1= "qwerty", String2= "qywter". Now these Strings contain same characters but are in different sequence. So is there any function that can be used to show that these strings contain same characters?? Can equals() method do that???

所有帮助都表示赞赏。

推荐答案

char[] chars1 = string1.toCharArray();
char[] chars2 = string2.toCharArray();
Arrays.sort(chars1);
Arrays.sort(chars2);

return Arrays.equals(chars1, chars2);
