Write a method to multiply two matrices. The header of the method is:public static double[][]multiplyMatrix(double[][] 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 cbe the result of the multiplication. Assume the column size of matrix a is n. Each element c_ij is a_i1 ? b_1j + a_i2 ? b_2j + c + a_in ? b_nj.For example, for two 3 ? 3 matrices a and b, c is

where c_ij = a_i1 ? b_1j + a_i2 ? b_2j + a_i3 ? b_3j.Write a test program that prompts the user to enter two 3 ? 3 matrices and displays their product. Here is a sample run:
