Checking if two strings are permutations of each other

Question

How to determine if two strings are permutations of each other

Answer 1

public class TwoStrgPermutation {

public int checkForUnique(String s1, String s2)
{
    int[] array1 = new int[256];
    int[] array2 = new int[256];

    array1 = arrayStringCounter(array1,s1);
    array2 = arrayStringCounter(array2,s2);

    if(Arrays.equals(array1, array2))
        return 0;
    else
        return 1;
}

public int[] arrayStringCounter(int[] array,String s)
{
    int val;
    for(int i=0;i0)
            {
                System.out.println("no it is not");
            }
        }
        else
        {
            System.out.println("no it is not");
        }

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}
