Write A Java Program That Fills A 3×4 Matrix With Random Numbers

 Write a Java program that fills a 3×4 matrix with random numbers in [0, 9] and calculates the sum of the elements in each row.

For example: 0 3 2 7 1 →sum =12

                         6 0 3 1    →sum =12

                         5 1 4 8] → sum =18

Use a two-dimensional array to store the matrix elements.

2) Write a Java program that adds two 4×4 matrices and prints the resulting matrix.

For example: [0 1 27 [1 10 2 [1 2 2 9 3120 3 267 6 3 8 7 5 1 44 4 03 2 9 1 7 6 Use two-dimensional arrays to store the elements of the matrices.

Your program should initialize the matrices in the declaration line.
