Transpose of matrix (without using second array)

CODE:

import java.util.*;

class Transpose1

{

     public static void main(String args[])

     {

           int m,i,j,temp;

           Scanner sc = new Scanner(System.in);

           System.out.print("Enter value for m :");

           m=sc.nextInt();

           int a[][]=new int[m][m];

           System.out.println("Matrix A");

           for(i=0;i<=m-1;i++)

           {

                for(j=0;j<=n-1;j++)

                {

                     System.out.print("enter a no:");

                     a[i][j]=sc.nextInt();

                }

           }

           for(i=0;i<=m-1;i++)

           {

                for(j=0;j<=n-1;j++)

                {

                     temp=a[i][j];

                     a[i][j]=a[j][i];

                     a[j][i]=temp;

                }

           }

           System.out.println("Transpose Matrix");

           for(i=0;i<=m-1;i++)

           {

                for(j=0;j<=n-1;j++)

                {

                     System.out.print(a[i][j]+"/t");

                }

                System.out.println();

           }

     }

}
