Please write in java! Please use directions in picture! Two different programs, 8.5 add two matrices, and 8.6 multiply two matrices. Thank you!

CSCI 1302 Lab # 4 Multidimensional Arrays Programming Exercise 8.5 (Algebra: add two matrices) Write a method to add two matrices. The header of the method is as follows: public static double[J[] 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 cij is aij + bij. For example, for two 3 * 3 matrices a and b, c is Write a test program that prompts the user to enter two 3 3 matrices and displays their sum. Here is a sample run Programming Exercise 8.6 (Algebra: multiply two matrices) Write a method to multiply two matrices. The header of the method is: public static double[]C] multiplyMatrix(double[J[] a, double[][) b) To multiply matrix a by matrix b, the number of columns in a must be the same as the number of rows in b, and the two matrices must have elements of the same or compatible types. Let c be the result of the multiplication. Assume the column size of matrix a is n. Each element cij is ai1 * b1j+ ai2 b2j + c+ ain * bnj. For example, for two 3 3 matrices a and b, cis where cij = ail * bl] + ai2 * b2] + ai3" b3j. Write a test program that prompts the user to enter two 3 3 matrices and displays their product.
