Hollow Rhombus Pattern in Java with Source Code; We’ve built the Hollow Rhombus asterisk/star pattern program in four different ways below, each with a sample example and output.

We have included a downloadable zip file at the end of the program so that you may run the following codes.

Example Program:

//Hollow Rhombus Pattern in Java : Sample Code    

package hollowrhombuspattern;

import java.util.Scanner;


public class HollowRhombusPattern {

   
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter Number : ");
        int n = sc.nextInt();

        System.out.print("Enter Symbol : ");

        char c = sc.next().charAt(0);

        for (int i = 1; i <= n; i++) {

            for (int j = 1; j <= n - i; j++) {
                System.out.print(" ");
            }
            if (i == 1 || i == n) {
                for (int j = 1; j <= n; j++) {
                    System.out.print(c);
                }
            } else {
                for (int j = 1; j <= n; j++) {
                    if (j == 1 || j == n) {
                        System.out.print(c);
                    } else {
                        System.out.print(" ");
                    }
                }
            }
            System.out.println();

        }

    }
}

Output:
