Introduction

In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

import java.util.Scanner;
public class Javaexcercise
{
    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(" ");
        }
    }
}

Result
