Number pyramid program in Java

import java.util.Scanner;
public class NumberPyramid
{
 public static void main(String[] args) {
  int num;
  Scanner sc = new Scanner(System.in);
  System.out.print("Enter number of rows : ");
  num = sc.nextInt();
  for (int r = 1; r <= num; r++) {
   for (int sp = num - r; sp >= 1; sp--) {
    System.out.print(" ");
   }
   for (int c = 1; c <= r; c++) {
    System.out.print(" " + c);
   }
   System.out.println();
  }
 }
}

Output:

Enter number of rows : 6
