Checking if two strings are permutations of each other

Question

How to determine if two strings are permutations of each other

Answer 1

I did this, and it works well and quickly:

public static boolean isPermutation(String str1, String str2)
{
    char[] x = str1.toCharArray();
    char[] y = str2.toCharArray();
    Arrays.sort(x);
    Arrays.sort(y);
    if(Arrays.equals(x, y))
        return true;
    return false;
}
