Object:- Write a Program in java to Find Transpose of Matrix

import java.util.Scanner;
public class Transpose
{
    public static void main(String args[])  
    {
	int i, j;
	System.out.println("Enter total rows and columns: ");
	Scanner s = new Scanner(System.in);
	int row = s.nextInt();
	int column = s.nextInt();
	int array[][] = new int[row][column];
	System.out.println("Enter matrix:");
 	for(i = 0; i < row; i++)
  	{
   	    for(j = 0; j < column; j++) 
     	    {
        	array[i][j] = s.nextInt();
        	System.out.print(" ");
            }
  	}
	System.out.println("The above matrix before Transpose is ");
  	for(i = 0; i < row; i++)
    	{
      	    for(j = 0; j < column; j++)
            {
          	System.out.print(array[i][j]+" ");
            }
            System.out.println(" ");
        }
 	System.out.println("The above matrix after Transpose is ");
  	for(i = 0; i < column; i++)
    	{
      	    for(j = 0; j < row; j++)
            {
                System.out.print(array[j][i]+" ");
            }
            System.out.println(" ");
        }
    }
}

Output

Enter total rows and columns: 
3 3
Enter matrix:
1
2
3
4
5
6
7
8
9
The above matrix before Transpose is 
1 2 3  
4 5 6  
7 8 9  
The above matrix after Transpose is 
1 4 7  
2 5 8  
3 6 9

Explanation

Enter the elements of array as input. We obtain the transpose of given matrix by interchanging all the rows and columns of a matrix with the help of loops.
