Programming Exercise 8.6 (Algebra: multiply two matrices) Write a method to multiply two matrices. The header of the method is: public static double[J[] multiplyMatrix(double[10 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 * bij ai2 b2j + c+ ain bnj. For example, for two 3 * 3 matrices a and b, c is where cij = ail * bij + ai2 * b2) + ai3 * b3j. Write a test program that kompts the user to enter two 3 3 matrices and displays their product. Here is a sample run
