Anagram in Java

Write a Program in Java to input a word and print its anagrams.
import java.util.*;
class Anagrams
{
    int c = 0;
   
    void input()
    {
        Scanner sc = new Scanner(System.in);
        System.out.print("Enter a word : ");
        String s = sc.next();
        System.out.println("The Anagrams are : ");
        display("",s);
        System.out.println("Total Number of Anagrams = "+c);
    }//input
 
    void display(String s1, String s2)
    {
        if(s2.length()<=1)
        {
            c++;
            System.out.println(s1+s2);
        }
        else
        {
            for(int i=0; i<s2.length(); i++)
            {
                String x = s2.substring(i, i+1);
                String y = s2.substring(0, i);
                String z = s2.substring(i+1);
                display(s1+x, y+z);
            }
        }
    }//display
   
    public static void main(String args[])
    {
        Anagrams ob=new Anagrams();
        ob.input();
    }//main
}//End of class
OUTPUT---
Enter a word : ANIK
The Anagrams are :
ANIK
ANKI
AINK
AIKN
AKNI
AKIN
NAIK
NAKI
NIAK
NIKA
NKAI
NKIA
IANK
IAKN
INAK
INKA
IKAN
IKNA
KANI
KAIN
KNAI
KNIA
KIAN
KINA
Total Number of Anagrams = 24

Sort Boundary Elements Of A Matrix

ISC COMPUTER SCIENCE PRACTICALS 2009 BOUNDARY ELEMENTS Write a program to declare a matrix A[ ][ ] of order (m*n) where 'm' is the number of rows and n is the number of columns such that both m and n must be greater than 2 and less than 20. Allow the user to input positive integers into this matrix. Perform the following tasks on the matrix: (a) Sort the elements of the outer row and column elements in ascending order using any standard sorting technique. (b) Calculate the sum of the outer row and column elements. (c) Output the original matrix, rearranged matrix, and only the boundary elements of the rearranged array with their sum. Test your program for the following data and some random data. 1. Example : INPUT : M=3, N=3 1 7 4 8 2 5 6 3 9 OUTPUT : ORIGINAL MATRIX : 1 7 4 8 2 5 6 3 9 REARRANGED MATRIX : 1 3 4 9 2 5 8 7 6 BOUNDARY ELEMENTS : 1 3 9 8   4 5 7 6 SUM OF OUTER ROW AND OUTER COLUMN = 43     ISC COMPUTER SCIENCE PRACTICALS 2009 ...
