Question

Write a method to add two matrices. The header of
the method is as follows:
public static double[][] addMatrix(double[][] a, double[][] b)

In order to be added, the two matrices must have the same dimensions and the
same or compatible types of elements. Let c be the resulting matrix. Each element
c_ij is a_ij + b_ij. For example, for two 2 x 2 matrices a and b, c is given.

Write a test program that prompts the user to enter two 2 x 2 matrices and
displays
their sum. Here is a sample run: ↵Enter
Enter matrix1: 1 2 3 4 ↵Enter
Enter matrix2: 0 2 4 1
The matrices are added as follows
1.0 2.0 0.0 2.0 1.0 4.0
3.0 4.0 + 4.0 1.0 = 7.0 5.0
