Number pattern

public class Numbertriangle6 {
 public static void main(String[] args) 
 {
int p=1;
 int n=4;
 for (int i = n; i >= 1; i--)
 {
 for (int j = 1; j <= i; j++) 
 {
 if(i==1)
 {
 System.out.print(" ");
 }
 System.out.print(p++ +" "); 
 System.out.print(" ");
 } 
 System.out.println();
 System.out.print(" ");
 if(i==3)
 {
 System.out.print(" ");
 }
 }
}
}

Output:-

  1  2  3  4 
   5  6  7 
    8  9
