Java find transpose of matrix

The given code determine the transpose of a matrix.The transpose of a matrix is formed by interchanging the rows and columns of a matrix such that row i of matrix becomes column i of the transposed matrix. The transpose of A is denoted by AT. Through the following code,the user is allowed to enter the number of rows and columns and the elements to create a matrix. Then using the for loop statements, turn all the rows of the matrix into columns and vice-versa.

import java.util.*;

    public class Transpose {
            public static void main(String[] args) throws Exception {
