I want to write a matrix multiplication progarm, but something is going wrong

package Matrix;
import java.util.Scanner;
class Matrix {
  public static void main (String args[]) {
      Scanner input = new Scanner(System.in);
        int m = 0;
        int n = 0;
         int array[][] = {{m},{n}};
        int p = 0;
             int[][] c = new int[array.length][array[0].length];
    int num;
    double[][] ID;
    ID = new double[n][m];
   System.out.println("enter rows:");
   n = input.nextInt();
   System.out.println("enter col:");
   m = input.nextInt();

  System.out.println("enter numbers["+n+"],
              ["+m+"]:");
    for (int row=0; row < n; row++) {
      for (int col=0; col < m; col++) {
   num = input.nextInt();
        }
      }
        int s = 0;
         int array1[][] = {{n},{p}};
     int num1;
    double[][] IDe;
    IDe = new double[n][p];
   System.out.println("enter rows:");
   n = input.nextInt();
   System.out.println("enter col:");
   p = input.nextInt();
   System.out.println("enter numbers["+n+"],
                 ["+p+"]:");
    for (int row=0; row < n; row++) {
      for (int col=0; col < p; col++) {
   num1 = input.nextInt();
        }
      }
    }
 
 for (int i=0; i<m; i++){
   for (int j=0; j<p; j++){
      for (int k=0; k<n; k++){
         c[i][j] += array[i][k]*array1[k][j];

    
        }
      }
     }
}
