Number triangle pyramid program in Java

import java.util.Scanner;
public class NumberTriangle
{
public static void main(String[] args)
{
int num;
System.out.print("Enter loop repeat number(rows): ");
Scanner sc = new Scanner(System.in);
num = sc.nextInt();
for (int r = 1; r <= num; r++) {
for (int sp = 1; sp <= num - r; sp++) {
System.out.print(" "); //it is 2 blank space
}
for (int c = 1; c <= 2 * r - 1; c++) {
System.out.print(" " + c);
}
System.out.println();
}
}
}

Output:

Enter loop repeat number(rows): 5
