Java Program for Number Pattern of Half Diamond.





package demo;
import java.util.Scanner;
public class HalfDaimond 
{
 public static void main(String[] args) 
 {
  int num, q;
  Scanner sc = new Scanner(System.in);
  System.out.print("Enter Seeding Number : ");
  num = sc.nextInt();
  for (int r = 1, n = num; r <= num; r++, n--) {
   for (int c = r, p = n; c >= 1; c--, p++) {
    System.out.print(p);
   }
   for (int c = r, p = num - 1; c > 1; c--, p--) {
    System.out.print(p);
   }
   System.out.println();
  }
  for (int r = 1; r < num; r++) {
   for (int c = r, p = r + 1; c < num; c++, p++) {
    System.out.print(p);
   }
   for (int c = num - r, p = num - 1; c > 1; c--, p--) {
    System.out.print(p);
   }
   System.out.println();
  }
 }
}


Output:
