Pattern Program in java Part-1

#1 Java Program To print Numbers in Below pattern:

              1
             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.   }
30.  
31. }
32.  
33. }
34. 
    
35. }

Output:

1.               1
