matrix multiplication using java


class MatrixMultiply{
public static void main(String[] args)  {
int array[][] = {{5,6,7},{4,8,9}};
int array1[][] = {{6,4},{5,7},{1,1}};
int array2[][] = new int[3][3];
int x= array.length;
System.out.println("Matrix 1 : ");
    for(int i = 0; i < x; i++) {
for(int j = 0; j <= x; j++) {
System.out.print(" "+ array[i][j]);
}
System.out.println();
}
int y= array1.length;
System.out.println("Matrix 2 : ");
    for(int i = 0; i < y; i++) {
for(int j = 0; j < y-1; j++) {
System.out.print(" "+array1[i][j]);
}
System.out.println();
        }

    for(int i = 0; i < x; i++) {
for(int j = 0; j < y-1; j++) {
for(int k = 0; k < y; k++){

array2[i][j] += array[i][k]*array1[k][j];
}
}
        }
System.out.println("Multiply of both matrix : ");
for(int i = 0; i < x; i++) {
for(int j = 0; j < y-1; j++) {
System.out.print(" "+array2[i][j]);
}
System.out.println();
        }
    }
