Java Program to Print Alphabet A using stars

Write a Java Program to Print Alphabet A using stars with an example. In this Java Alphabet A pattern example, we used nested for loop and if statement to print the output.

package ShapePrograms;

import java.util.Scanner;

public class AlphabetA {
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Please Enter the Number =  ");
		int rows = sc.nextInt();
		
		System.out.println("---- Printing Alphabet A ------");
		
		for (int i = 0 ; i < rows; i++ ) 
		{
			for (int j = 0 ; j <= rows/2; j++ ) 
			{
				if((i == 0 && j != 0 && j != rows/2) || i == rows / 2 ||
						(j == 0 || j == rows /2 ) && i != 0)
					System.out.print("*");
				else
					System.out.print(" ");
			}
			System.out.println("\n");
		}
	}
}
Java Program to Print Alphabet A using stars 1

In this Java Alphabet A using stars pattern example, we replaced the for loop with a while loop.

package ShapePrograms;

import java.util.Scanner;

public class AlphabetA2 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Please Enter the Number =  ");
		int rows = sc.nextInt();
		
		System.out.println("---- Printing Alphabet A ------");
		
		int j, i = 0;
		
		while ( i < rows ) 
		{
			j = 0 ;
			
			while ( j <= rows/2) 
			{
				if((i == 0 && j != 0 && j != rows/2) || i == rows / 2 ||
						(j == 0 || j == rows /2 ) && i != 0)
					System.out.print("*");
				else
					System.out.print(" ");
				j++;
			}
			System.out.println("\n");
			i++;
		}
	}
}
Please Enter the Number =  7

Java Program to Print Alphabet A using stars using do while loop.

package ShapePrograms;

import java.util.Scanner;

public class AlphabetA3 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);

		System.out.println("---- Printing Alphabet A ------");
		
		int j, i = 0;
		
		do
		{
			j = 0 ;
			
			do
			{
				if((i == 0 && j != 0 && j != rows/2) || i == rows / 2 ||
						(j == 0 || j == rows /2 ) && i != 0)
					System.out.print("*");
				else
					System.out.print(" ");
				
			} while ( ++j <= rows/2);
			
			System.out.println("\n");

		} while ( ++i < rows ) ;
	}
}
Please Enter the Number =  10
