                {

                                BufferedReader input =( new InputStreamReader (System.in));

                               

                                System.out.print("ordo matriks = 2*2");

                int [][] matrik = new int [2][2];

                               

                                System.out.println("masukan elemen matriksnya:");

                                for(int i=0;i<2;i++)

                                {

                                                for(int j=0;j<2;j++)

                                                {

                                                  System.out.print("elemen ["+(i+1)+","+(j+1)+"]=");

                                                  matrika[i][j]=Integer.parseInt(input.readLine());

                                                 

                                                 }
