Java Program to Print Alphabet B Pattern

In this article, we will show the list of Java programs that print the star pattern of the alphabet from A to Z (A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z) using the for loop, while loop, and functions with an example.

Java Program to Print Alphabet B Pattern

In this Java pattern program, we show the steps to print the stars in an Alphabet B shape or pattern using for loop, while loop, and functions.

import java.util.Scanner;

public class Example 
{
	private static Scanner sc;
	
	public static void main(String[] args) 
	{
		sc = new Scanner(System.in);
		
		System.out.print("Enter Numbers of Rows = ");
		int rows = sc.nextInt();
		
		for (int i = 0 ; i < rows; i++ )
		{
			System.out.printf("*");
			for (int j = 0 ; j < 2 * rows - 1; j++ )
			{
				if ((i == 0 || i == rows - 1 || i == rows / 2) && (j < (2 * rows) - 2))
				{
					System.out.printf("*");
				}
				else if ((j == (2 * rows) - 2) &&  !(i == 0 || i == rows - 1 || i == rows / 2))
				{
					System.out.printf("*");
				}
				else
				{
					System.out.printf(" ");
				}
			}
			System.out.println();
		}
	}
}

Enter Numbers of Rows = 15

Within this Alphabet B shape or Pattern program in Python, we replaced the Python for loop syntax with a Python while loop to print the stars at each position.

import java.util.Scanner;

public class Example 
{
	private static Scanner sc;
	
	public static void main(String[] args) 
	{
		sc = new Scanner(System.in);
		int rows, i, j;
		
		System.out.print("Enter Numbers of Rows = ");
		rows = sc.nextInt();
		
		i = 0 ;
		while (i < rows )
		{
			System.out.printf("*");
			j = 0 ;
			while ( j < rows - 1 )
			{
				if ((i == 0 || i == rows - 1 || i == rows / 2) && (j < rows - 2))

In this program, we created an AlphabetBShape function to print the Alphabet B Pattern or shape filled with stars on rows and columns. For more Java Alphabet Pattern programs and Java star pattern programs, please use the hyperlinks.

import java.util.Scanner;

public class Example 
{
	private static Scanner sc;
	
	public static void main(String[] args) 
	{
		sc = new Scanner(System.in);
		
		System.out.print("Enter Numbers of Rows = ");
		int rows = sc.nextInt();
		
		System.out.print("Enter Character = ");
		char a = sc.next().charAt(0);
		
		AlphabetBShape(rows, a);
	}
	public static void AlphabetBShape(int rows, char a) 
	{
		for (int i = 0 ; i < rows; i++ )
		{
			System.out.printf("%c", a);
			for (int j = 0 ; j < rows - 1; j++ )
			{
				if ((i == 0 || i == rows - 1 || i == rows / 2) && (j < rows - 2))
				{
					System.out.printf("%c ", a);
				}
				else if ((j == rows - 2) &&  !(i == 0 || i == rows - 1 || i == rows / 2))
				{
					System.out.printf("%c ", a);
				}
				else
				{
					System.out.printf("  ");
				}
			}
			System.out.println();
		}	
	}
