Java Program to Print Downward Triangle of Mirrored Alphabets Pattern

Write a Java program to print downward triangle of mirrored alphabets pattern using for loop.

package Alphabets;

import java.util.Scanner;

public class DownwardTriMirrorAlp1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Downward Triangle of Mirrored Alphabets Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("The Downward Triangle of Mirrored Alphabets Pattern");
		int alphabet = 65;
		
		for (int i = 0; i <= rows - 1; i++ ) 
		{
			for (int j = i; j <= rows - 1; j++ ) 	
			{
				System.out.print((char)(alphabet + j) + " ");
			}
			for(int k = rows - 2; k >= i; k--)
			{
				System.out.print((char)(alphabet + k) + " ");
			}
			System.out.println();
		}
	}
}

In this Java pattern example, we used the while loop to display the downward triangle pattern of mirrored alphabets.

package Alphabets;

import java.util.Scanner;

public class DownwardTriMirrorAlp2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Downward Triangle of Mirrored Alphabets Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Downward Triangle of Mirrored Alphabets Pattern\n");
		int alphabet = 65;
		int j, k, i = 0;
		
		while( i <= rows - 1 ) 
		{
			
			j = i;
			while(j <= rows - 1 ) 	
			{
				System.out.print((char)(alphabet + j) + " ");
				j++;
			}
			
			k = rows - 2;
			while(k >= i)
			{
				System.out.print((char)(alphabet + k) + " ");
				k--;
			}
			System.out.println();
			i++;
		}
	}
}

Enter Downward Triangle of Mirrored Alphabets Rows = 15
