             2 3
            4 5 6
           7 8 9 10
         11 12 13 14 15




  1. package com.javatutorial;
  2. public class NumbersFormat {
  3.  
  4.  public static void main(String[] args) {
  5.  
  6.  int num=15;
  7.  int temp=1;
  8.      
  9.  for (int i = 1; i <= num; i++)
  10.  {
  11.  
  12.   for (int k = i; k <num; k++)
  13.    System.out.print(" ");
  14.    for (int j =1; j <= i; j++){
  15.  
  16.     System.out.print("" +temp+ " ");
  17.      temp++;
  18.  
  19.  if(temp>15){
  20.        break;
  21.  }
  22.  
  23.  }
  24.  
  25.   System.out.println();
  26.  
  27. if(temp>15){
  28.      break;
  29.   }
