Thread: diamond pattern and loop

Dear Friends
I am trying to write a program to display a diamond pattern based on the user input size.
The output must like this below :

Please type an integer number: 4
********
***##***
**####**
*######*
*######*
**####**
***##***
********

But when I wrote my Java program , it gives the out put below

Please type an integer number:  4
****
***##
**####
*######
**#######
***#####
****###

And this is my Java program .

import java.util.Scanner; 
public class DiamondPattern2{
	public static void main(String[] args){
	Scanner keyboard = new Scanner(System.in);
 
		System.out.print("Please type an integer number:  ");
		int n = keyboard.nextInt();
 
		for (int i = 1; i <= n; i++){
			System.out.print("*");
      for (int j = 0; j < (n - i); j++)
			System.out.print("*");
		for (int j = 2; j <= i; j++)
			System.out.print("#");
		for (int k = 2; k < (i+1); k++)
			System.out.print("#");
 
			System.out.println();
			}
 
 		for (int i = n - 1; i >= 1; i--){
			System.out.print("*");
      for (int j = 0; j < (n - i); j++)
			System.out.print("*");
		for (int j = 0; j <= (i*2); j++)
			System.out.print("#");
		for (int k = n; k <= (i); k++)
			System.out.print("#");
 
         System.out.println();
 
         }
 
      }
 
	}

I don't know how to continue to complete s on the other side and fix # . Anyone can fix my program ?
Thanks
Naif

Thanks for reply , could you help me more to add the codes? Please

yes, could you help me with the first part ?
