Java Find Transpose of Matrix

```import java.util.*;

public class Transpose {
public static void main(String[] args) throws Exception {
int rows, cols;
int[][] matrix, tmatrix;
Scanner input = new Scanner(System.in);
System.out.print("Enter number of rows: ");
rows = input.nextInt();
System.out.print("Enter number of columns: ");
cols = input.nextInt();
matrix = new int[rows][cols];
tmatrix = new int[cols][rows];
System.out.println("Enter elements for Matrix");
for (int i = 0; i < rows; i++) {
for (int j = 0; j < cols; j++) {
matrix[i][j] = input.nextInt();
}
}
for (int i = 0; i < rows; i++) {
for (int j = 0; j < cols; j++) {
tmatrix[i][j] = matrix[j][i];
}
}
System.out.println("Matrix is:");
for (int i = 0; i < rows; i++) {
for (int j = 0; j < cols; j++) {
System.out.print(matrix[i][j] + " ");
}
System.out.println();
}
System.out.println("Its transpose is: ");
for (int i = 0; i < cols; i++) {
for (int j = 0; j < rows; j++) {
System.out.print(tmatrix[i][j] + " ");
}
System.out.println();
}
}
}
