JAVA Program for Rhombus Star Pattern

Printing Rhombus Star Pattern

In this JAVA program we will be coding a rhombus star pattern which will have n number of stars in it rows and n of stars in column hence it will be a n x n rhombus star pattern

Printing Pattern

In this JAVA program we will be coding a rhombus star pattern which will have n number of stars in it rows and n of stars in column hence it will be a n x n rhombus star pattern

Prerequisite:

Basic knowledge of Java language and loops

Algorithm:

  • Take the number of rows as input from the user and store it in any variable.(‘row‘ in this case).
  • Take the number of coloum as input from the user and store it in any variable.(‘col‘ in this case).
  • Run a loop ‘row’ number of times to iterate through each of the rows. From i=1 to i<=row. The loop should be structured as for                                     (int i=1; i<= row; i++)
  •  Run a nested loop inside the main loop to print the spaces before the rhombus. From j=1 to j<=i. The loop should be structured as for( j=1; j<=i ; j++).
  • Run another nested loop inside the main loop after the previous loop to print the stars in each column of a row. From j=1 to j<=col. The loop should be structured as for( j=1 ; j<=col ; j++).
  • Move to the next line by printing a new line . System.out.print(“*”);
  • After that take System.out.println(); at the end of main for loop

Code in Java:

import java.util.Scanner;
public class Pattern1 {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		System.out.println("Enter row and col");
		int row = sc.nextInt();
		int col = sc.nextInt();
		
		for (int i=1; i<= row; i++) {
			for (int j=1 ; j<=i ; j++)  // this loop is for printing spaces
				System.out.print(" ");
			for (int j=1 ; j<=col; j++) // this loop is for printing stars
				System.out.print("*");
			System.out.println();
		}

	}

}
