Write an interactive program to print a diamond shape. For example, if user enters the number 3

import java.util.Scanner;

public class demo {

    public static void main(String[] args) {

        int i, j, k;
        Scanner scan = new Scanner(System.in);
        int no = scan.nextInt();

        for (i = 0; i < no; i++) {

            for (j = (no / 2) + 1; j >= i; j--) {
                System.out.print(" ");
            }

            for (k = 0; k <= i; k++) {
                System.out.print("* ");
            }
            System.out.println();
        }
        for (i = 0; i < no; i++) {
            System.out.print(" ");

            for (j = 0; j <= i; j++) {
                System.out.print(" ");
            }

            for (k = no - 1; k > i; k--) {
                System.out.print("* ");
            }
            System.out.println();
        }

    }
