Java Program to Print Triangle of Mirrored Alphabets Pattern

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

package Alphabets;
import java.util.Scanner;

public class TriangleMirroredAlp1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Triangle of Mirrored Alphabets Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Triangle of Mirrored Alphabets Pattern");
		
		int alphabet = 65;
		
		for (int i = 0; i <= rows - 1; i++) 
		{
			for (int j = rows - 1; j >= i; j-- ) 	
			{
				System.out.print(" ");
			}
			for(int k = 0; k <= i; k++)
			{
				System.out.print((char)(alphabet + k));
			}
			for(int l = i - 1; l >= 0; l--)
			{
				System.out.print((char)(alphabet + l));
			}
			System.out.println();
		}
	}
}

This Java pattern example prints the triangle of mirrored alphabets using while loop.

package Alphabets;

import java.util.Scanner;

public class TriangleMirroredAlp2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Triangle of Mirrored Alphabets Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Triangle of Mirrored Alphabets Pattern");
		
		int i, j, k, l, alphabet = 65;
		
		i = 0;
		while(i <= rows - 1) 
		{
			j = rows - 1;
			while(j >= i ) 	
			{
				System.out.print(" ");
				j--;
			}
			
			k = 0;
			while(k <= i)
			{
				System.out.print((char)(alphabet + k));
				k++;
			}
			
			l = i - 1;
			while( l >= 0)
			{
				System.out.print((char)(alphabet + l));
				l--;
			}
			System.out.println();
			i++;
		}
	}
}
