Java program to print a Rhombus pattern using star

Java program to print Rhombus pattern using star or any character :

In this tutorial, we will show you how to print a Rhombus in Java. We can print the Rhombus using any character like *,&,$ etc. In this example, we are using ‘for’ loop.But instead of ‘for’, we can also use ‘while’ or ‘do-while’ loop.

The output will look as like below :

******
 ******
  ******
   ******
    ******
     ******

Using one loop, we will print each line.

For the first line , no spaces are added before the stars.
For the 2nd line, one space,for the 3rd line, two spaces etc.
Print the spaces first and then print the stars. After printing the stars, print a new line. That’s it.

We are using the ‘Scanner’ class to take the input from the users : The size of the Rhombus and the character used to print it.

Program :

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int size;
        Character c;

        System.out.println("Enter size of the Rhombus : ");
        size = sc.nextInt();

        System.out.println("Which character you want to use : ");
        c = sc.next().charAt(0);

        for (int row = 0; row < size; row++) {
            //first print the space
            for (int space = size - row; space < size; space++) {
                System.out.print(" ");
            }

            //print the character
            for (int i = 0; i < size; i++) {
                System.out.print(c);
            }

            //add a newline
            System.out.println();
        }

    }

}

Example 1 :

Enter size of the Rhombus :
6
Which character you want to use :
*
******
 ******
  ******
   ******
    ******
     ******

Example 2 :

Enter size of the Rhombus :
8
Which character you want to use :
&
&&&&&&&&
 &&&&&&&&
  &&&&&&&&
   &&&&&&&&
    &&&&&&&&
     &&&&&&&&
      &&&&&&&&
       &&&&&&&&
