Java Program to Print K Shape Alphabets Pattern

Write a Java program to print K shape alphabets pattern using for loop.

package Alphabets;

import java.util.Scanner;

public class kShapeAlphabets1 {

	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		int i, j, alphabet;
		
		System.out.print("Enter K Shape Alphabets Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing K Shape Alphabets Pattern");		
		
		for (i = rows - 1; i >= 0; i-- ) 
		{
			alphabet = 65;
			for (j = 0 ; j <= i; j++ ) 	
			{
				System.out.print((char)(alphabet + j) + " ");
			}
			System.out.println();
		}
		
		for (i = 1 ; i < rows; i++ ) 
		{
			alphabet = 65;
			for (j = 0 ; j <= i; j++ ) 	
			{
				System.out.print((char)(alphabet + j) + " ");
			}
			System.out.println();
		}
	}
}
Java Program to Print K Shape Alphabet Pattern

This Java example displays the alphabets arranged in K shape pattern using a while loop.

package Alphabets;

import java.util.Scanner;

public class kShapeAlphabets2 {

	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter K Shape Alphabets Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing K Shape Alphabets Pattern");		
		int i = rows - 1, j, alphabet;
		
		while (i >= 0 ) 
		{
			alphabet = 65;
			j = 0 ;
			while ( j <= i) 	
			{
				System.out.print((char)(alphabet + j) + " ");
				j++;
			}
			System.out.println();
			i--;
		}
		
		i = 1 ;
		while ( i < rows ) 
		{
			alphabet = 65;
			j = 0 ;
			while ( j <= i ) 	
			{
				System.out.print((char)(alphabet + j) + " ");
				j++;
			}
			System.out.println();
			i++;
		}
	}
}
Enter K Shape Alphabets Pattern Rows = 7
