I'm not sure but try this import java.util.*; public class le1{ public static void main(String[] args) { Scanner scan = new Scanner(System.in); int N = scan.nextInt(); int M = scan.nextInt(); int[][] array = new int[N][M]; //1 matrix Random r = new Random(); for (int i = 0 ;i<N ;i++ ) { for (int j = 0;j<M ;j++ ) { array[i][j]=scan.nextInt(); } } System.out.println(); int N1 = scan.nextInt(); int M1 = scan.nextInt(); int[][] array2 = new int[N1][M1]; //2 matrix for (int i = 0 ;i<N1 ;i++ ) { for (int j = 0;j<M1 ;j++ ) { array2[i][j]=scan.nextInt(); } } System.out.println(); if (M==N1) { int[][] result_array = new int[N][M1]; for (int i = 0;i<N ;i++ ) { //Multiplication for (int j =0;j<M1 ;j++ ) { for (int k = 0;k<N ;k++ ) { result_array[i][j]+=array[i][k]*array2[k][j]; } } } for (int i = 0;i<N ;i++ ) { //Printing for (int j = 0;j<M1 ;j++ ) { System.out.print(result_array[i][j]+" "); } System.out.println(); } }else{ System.out.println("Error"); } } }
