Java Program to Print Diamond Star Pattern

Last Updated: 19 July, 2022

On this tutorial page, we are going to learn how to write a Java program to print the diamond star pattern.

A pattern program is composed of two or more loop statements and print statements.

Let's see the Java Program Implementation.

Program: Diamond Star Pattern Program in Java

  public class DiamondShapePattern {
    public static void main(String args[]) {
      int row, column, numberOfRows = 5, space = 1;
  
      space = numberOfRows - 1;
  
      for (row = 1; row <= numberOfRows; row++) {
        for (column = 1; column <= space; column++) {
          System.out.print(" ");
        }
        space--;
        for (column = 1; column <= 2 * row - 1; column++) {
          System.out.print("*");
        }
        System.out.println("");
      }
  
      space = 1;
  
      for (row = 1; row <= numberOfRows - 1; row++) {
        for (column = 1; column <= space; column++) {
          System.out.print(" ");
        }
        space++;
        for (column = 1; column <= 2 * (numberOfRows - row) - 1; column++) {
          System.out.print("*");
        }
        System.out.println("");
      }
    }
  }

Output

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

That's all guys, hope this Java Program is helpful for you.

Happy Learning... 😀
