Java Program to Print Right Triangle of Consecutive Alphabets Pattern

Write a Java program to print right triangle of consecutive alphabets pattern using for loop.

package Alphabets;
import java.util.Scanner;

public class RightTriConsecAlp1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Right Triangle of Consecutive Alphabets Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Right Triangle of Consecutive Alphabets Pattern");
		int alphabet = 65;
		
		for (int i = 0; i <= rows - 1; i++) 
		{
			for (int j = 0; j <= i; j++ ) 	
			{
				System.out.print((char)(alphabet++) + " ");
			}
			System.out.println();
		}
	}
}
Java Program to Print Right Triangle of Consecutive Alphabets Pattern

This Java program prints the right angled triangle pattern of consecutive alphabets using while loop.

package Alphabets;

import java.util.Scanner;

public class RightTriConsecAlp2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Right Triangle of Consecutive Alphabets Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Right Triangle of Consecutive Alphabets Pattern");
		int alphabet = 65;
		
		int j, i = 0; 
		
		while(i <= rows - 1) 
		{
			j = 0;
			
			while(j <= i ) 	
			{
				System.out.print((char)(alphabet++) + " ");
				j++;
			}
			System.out.println();
			i++;
		}
	}
}

This Java example uses the do while loop to display the right angled triangle pattern of consecutive column alphabets.

package Alphabets;

import java.util.Scanner;

public class RightTriConsecAlp3 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Right Triangle of Consecutive Alphabets Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Right Triangle of Consecutive Alphabets Pattern");
		int alphabet = 65;
		
		int j, i = 0; 
		
		do
		{
			j = 0;
			
			do 	
			{
				System.out.print((char)(alphabet++) + " ");

			} while(++j <= i );
			
			System.out.println();

		} while(++i <= rows - 1);
	}
}
