Java Program to Display Transpose Matrix

Java Program to Find Transpose of Matrix

Transpose of a matrix is obtained by changing rows to columns and columns to rows. In other words, transpose of A[][] is obtained by changing A[i][j] to A[j][i].

Approach:

Create a 2-D Array.
Insert the values in the array by running two nested loops. The outer ith loop will go till the no.of rows and the inner jth loop will run till the number of columns.
For displaying the transpose of the matrix, run the same loop as explained in the above step but print the a[j[i] th element every time we are traversing inside the loop.

Example:

Java

// Java Program to Display Transpose Matrix 
  
import java.util.*; 
public class GFG { 
    public static void main(String args[]) 
    { 
        // initialize the array of 3*3 order 
        int[][] arr = new int[3][3]; 
  
        System.out.println("enter the elements of matrix"); 
  
        int k = 1; 
  
        // get the elements from user 
        for (int i = 0; i < 3; i++) { 
            for (int j = 0; j < 3; j++) { 
                arr[i][j] = k++; 
            } 
        } 
  
        System.out.println("Matrix before Transpose "); 
  
        // display original matrix 
        for (int i = 0; i < 3; i++) { 
            for (int j = 0; j < 3; j++) { 
                System.out.print(" " + arr[i][j]); 
            } 
            System.out.println(); 
        } 
  
        System.out.println("Matrix After Transpose "); 
  
        // transpose and print matrix 
        for (int i = 0; i < 3; i++) { 
            for (int j = 0; j < 3; j++) { 
                System.out.print(" " + arr[j][i]); 
            } 
            System.out.println(); 
        } 
    } 
}

Output

enter the elements of matrix
Matrix before Transpose 
 1 2 3
 4 5 6
 7 8 9
Matrix After Transpose 
 1 4 7
 2 5 8
 3 6 9
