Creating a Multiplication Table in Java

Problem:

Write an application called MultiplicationTable that asks the user to input a number N then creates a 2 dimensional array of size N X N and stores inside it the table of multiplication up to N.

Output:

Enter N: 4
Outputs:
1 2 3 4
2 4 12 8
3 6 9 12
4 8 12 16

Solution:

import java.util.Scanner;
public class Problem1 {
 public static void main(String[] args)
 {
  Scanner scan = new Scanner(System.in);
  int num = scan.nextInt();
  
  int[][] table = new int[num][num];
  
  for(int i=0; i<num; i++)
  {
   for(int j=0; j<num; j++)
   {
    table[i][j] = (i+1)*(j+1);
   }
  }
  
  for(int i=0; i<num; i++)
  {
   for(int j=0; j<num; j++)
   {
    System.out.print(table[i][j] + "\t");
   }
   System.out.println();
  }
  
 }
}
