Checking if two strings are permutations of each other

Question

How to determine if two strings are permutations of each other

Answer 1

To put @Michael Borgwardt's words in to code:

public boolean checkAnagram(String str1, String str2) {

    if (str1.length() != str2.length())
      return false;

    char[] a = str1.toCharArray();
    char[] b = str2.toCharArray();

    Arrays.sort(a);
    Arrays.sort(b);

    return Arrays.equals(a, b);
}
