Java Program to Print Right Triangle of Incremental Alphabets Pattern

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

package Alphabets;

import java.util.Scanner;

public class RightTriIncAlp1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Right Triangle of Incremented Characters Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Right Triangle of Incremented Row Characters Pattern");
		int alphabet = 65;
		
		for (int i = 0; i <= rows - 1; i++) 
		{
			for (int j = i; j >= 0; j-- ) 	
			{
				System.out.print((char)(alphabet + j) + " ");
			}
			System.out.println();
		}
	}
}

This Java example prints the right angled triangle pattern of incremental alphabets or ascending order using while loop.

package Alphabets;

import java.util.Scanner;

public class RightTriIncAlp2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Right Triangle of Incremented Characters Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Right Triangle of Incremented Row Characters Pattern");
		
		int i, j, alphabet = 65;
		
		i = 0;
		while(i <= rows - 1) 
		{
			j = i;
			while(j >= 0 ) 	
			{
				System.out.print((char)(alphabet + j) + " ");
				j--;
			}
			System.out.println();
			i++;
		}
	}
}

This Java program uses the do while loop to display the right angled triangle pattern of incremental alphabets.

package Alphabets;

import java.util.Scanner;

public class RightTriIncAlp3 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Right Triangle of Incremented Characters Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Right Triangle of Incremented Row Characters Pattern");
		
		int i, j, alphabet = 65;
		
		i = 0;
		do 
		{
			j = i;
			do 	
			{
				System.out.print((char)(alphabet + j) + " ");

			} while(--j >= 0 );
			
			System.out.println();

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