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. For more Alphabet examples, refer to the Java Alphabet Pattern Programs article.

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);
	}
}
