The program to this question can be given as:

Program:

import java. util.*; / /import package

public class Main / /defining class

{

public static int[][] transpose (int[][] a1) / /defining function transpose

{

int i, j; / /define variables

int[][] transpose = new int[a1[0]. length][a1. length]; / /define variable transpose.

//loop for transpose matrix.

for (i = 0; i < a1. length; i++)

{

for (j = 0; j < a1[i]. length; j++)

{

transpose [j][i] = a1[i][j]; / /hold value in transpose variable

}

}

return transpose; / /return transpose matrix.

}

public static void main (String[] args) / /main method.

{

int row, col, i, j; / /defining variable.

Scanner obj = new Scanner (System. in); / /creating Scanner class Object

System. out. print ("Enter number of rows: "); //message

row = obj. nextInt (); / /input rows form user.

System. out. print ("Enter number of columns: "); //message

col = obj. nextInt (); / /input columns form user.

int[][] a1 = new int[row][col]; / /defining array.

System. out. println ("Enter matrix"); / /message

/ / loop for input array elements from user

for (i=0; i
{

for (j=0; j
{

a1[i][j]=obj. nextInt (); / /input in array variable.

}

}

System. out. println ("Matrix you insert : "); / /message

/ / loop for display array.

for (i=0; i
{

for (j=0; j
{

System. out. print (a1[i][j]+" "); / /print matrix

}

System. out. print ("/n");

}

int[][] result = transpose (a1); / /define result array variable that holds function value.

System. out. println ("Transposed matrix is : ");

//use loop for print Transpose matrix.

for (i = 0; i < result. length; i++)

{

for (j = 0; j < result[i]. length; j++)

{

System. out. print (result[i][j] + " "); / /print matrix

}

System. out. print ("/n");

}

}

}

Output:

Enter number of rows: 2

Enter number of columns: 3

Enter matrix

2

3

4

9

8

7

Matrix you insert:

2 3 4

9 8 7

Transposed matrix is:

2 9

3 8

4 7

Explanation:

The description of the above program can be given as:

In the above program firstly import a package, then declare a class that is "Main" inside a class defining a transpose () function this function returns a matrix in transpose form. In the main class, we define a variable and matrix that is "row, col, i, j and a1[][]". Then we Creating a scanner class object, which is used by row, col and a1[][] variables for user input. The row and col variables are used to declare matrix size and i, j variable is used in the loop for insert and display matrix. a1[][] matrix is used for input matrix elements and passes into transpose () function as an argument that returns a value that is held in the result variable. This is used as a loop for the print transpose matrix.
