I have tried this much.
import java.util.Scanner;



/**This program displays a diamond pattern with the input gathered from user
*/


public class DiamondPattern {


public static void main(String[] args)
{
//Create a Scanner object for keyboard input.
Scanner keyboard = new Scanner(System.in);

//Get the character input from user.
System.out.print("Please enter what charecter you will be using?");

//Get integer input from user between 1-10.
System.out.print("Please enter the number for the size you want your diamond to be.");
