Matrix to find the difference between the two, matrices. The details of the members of the class are, given below:, Class name: Matrix, Data members/instance variables:, arr[][]: stores the matrix element, m: integer to store the number of rows, n: integer to store the number of columns, Member functions:, Matrix (int mm, int nn): to initialize the size of the, matrix m = mm and n = nn, void fillarray(): to enter the elements of the matrix, Matrix SubMat(Matrix A): subtract the current object, from the matrix of the parameterized object and, return the resulting object, void display(): display the matrix elements, , Specify the class Matrix giving details of the, constructor(int, int), void fillarray(), Matrix SubMat, (Matrix) and void display (). Define the main ( ), function to create objects and call the methods, accordingly to enable the task., , import java.util.*;, class matrix, {, int a[][],m,n;, matrix(int mm,int nn), {, m=mm;, n=nn;, a=new int[m][n];, }, void fillarray(), {, Scanner sc=new Scanner(System.in);, int i,j;, for(i=0;i<m;i++), {, for(j=0;j<n;j++), a[i][j]=sc.nextInt();, }, }, matrix submat(matrix A), {, matrix diff=new matrix(m,n);, , COMBINED ISC 135 Page 5
