How to Identify the Same Characters in 2 Different Strings

Question

Hi All,
I am requiring a suggestion on how to identify the same characters in 2 different Strings, for example:
String str1 = "hello";
String str2 = "llheo";
Both Strings contain the same characters, but in a different order, so what would be the best technique to verify t that both Strings indeed contain the same characters?
I was personally thinking along the lines of using the class, java.util.regex.Pattern?
Any thoughts would me much appreciated. Thanks

Answer 1

I would instead sort the characters, and then compare
the sorted data.
I'm fealing generous
    private static boolean anagram(String left, String right)
        if (left.length() != right.length())
            return false;
        char[] leftChars = left.toCharArray();
        char[] rightChars = right.toCharArray();
        Arrays.sort(leftChars);
        Arrays.sort(rightChars);
        return Arrays.equals(leftChars, rightChars);
    }
