To the TwoDArray class in Section 2.6 of the lecture notes, add a method called transpose() that generates the transpose of a 2D array with the same number of rows and columns (i.e., a square matrix). Add appropriate code in main() of the TwoDArrayApp class to execute the transpose() method and use the display() method to print the transposed matrix.

Sample Output:

Section 2.6 in class lecture is as follows:

The original matrix: 3 11 22 33 44 2 4 6 8 100 200 300 400 Column sum: 114 228 342 456 The matrix after being transposed: 11 2 100 2 22 4 200 3 33 6 300 4 44 8 400 WNP 1 2 3 /** * TwoDArray.java * / public class TwoDArray private int a[][]; private int nRows; public TwoDArray (int maxRows, int maxCols) // constructor a = new int [maxRows] (maxCols) ; nRows = 0; public void insert (int[] row) WWWNNNNNNNNNNPPPPPPPPPP on W NOOCs owocowanie w NPO a [nRows] = row; nRow3++; public void display ( ) for (int i = 0; i
