Java Program to Print Right Triangle of Consecutive Row Alphabets Pattern

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

package Alphabets;

import java.util.Scanner;

public class RightTriConsecRowAlp1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Right Triangle of Consec Row Alphabets Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Right Triangle of Consecutive Row Alphabets Pattern");
		int alphabet = 64;
		
		for (int i = 1; i <= rows; i++) 
		{
			int val = i;
			for (int j = 1; j <= i; j++ ) 	
			{
				System.out.print((char)(alphabet+ val) + " ");
				val = val + rows - j;
			}
			System.out.println();
		}
	}
}

This Java example pattern displays the right angled triangle of consecutive alphabets in each row using while loop. For more Alphabet examples, refer to the Java Alphabet Pattern Programs article.

package Alphabets;

import java.util.Scanner;

public class RightTriConsecRowAlp2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Right Triangle of Consecutive Row Alphabets Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Right Triangle of Consecutive Row Alphabets Pattern");
		int alphabet = 64;
		int val, j, i = 1; 
		
		while (i <= rows) 
		{
			val = i;
			j = 1;
			
			while( j <= i ) 	
			{
				System.out.print((char)(alphabet+ val) + " ");
				val = val + rows - j;
				j++;
			}
			System.out.println();
			i++;
		}
	}
}

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

package Alphabets;

import java.util.Scanner;

public class RightTriConsecRowAlp3 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Right Triangle of Consecutive Row Alphabets Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Right Triangle of Consecutive Row Alphabets Pattern");
		int alphabet = 64;
		int val, j, i = 1; 
		
		do
		{
			val = i;
			j = 1;
			
			do	
			{
				System.out.print((char)(alphabet+ val) + " ");
				val = val + rows - j;

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

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