a. Write a Java method named sumMajorDiagonal that takes one square 2D array called data and returns the sum of all the numbers in the major diagonal in an n x n matrix of double values. b. Write a Java class called TwoDimArray that: o Declares a 2D array variable with name arr2D with 4 rows and 4 columns. o Reads from the user the values to be saved in the 2D array arr2D. o Call the method sumMajorDiagonal() to compute the sum of all the numbers in the major diagonal in the 2D array arr2D. o Print the resultant sum of all the numbers in the major diagonal in the 2D array arr2D. Sample Run: Enter a 2D array with 4 rows and 4 columns: 1.0 2.9 3.76 4.06 2.8 6.5 4.50 5.49 7.7 5.2 11.6 4.11 1.8 2.4 3.35 16.0 Sum of the numbers in the major diagonal is 34.5 Explanation: 1.0 + 6.5 + 11.6 + 16.0 = 34.5 %3D
