Palindromic Alphabet Pyramid
This program prints a palindromic alphabet pyramid.
Problem Statement
Write a Java program that prints a palindromic alphabet pyramid with 5 rows.
Source Code
| 1 | public class PalindromicAlphabetPyramid { |
| 2 | public static void main(String[] args) { |
| 3 | int n = 5; |
| 4 | for(int i=1; i<=n; i++) { |
| 5 | for(int j=i; j<n; j++) System.out.print(" "); |
| 6 | for(char ch='A'; ch<'A'+i; ch++) System.out.print(ch); |
| 7 | for(char ch=(char)('A'+i-2); ch>='A'; ch--) System.out.print(ch); |
| 8 | System.out.println(); |
| 9 | } |
| 10 | } |
| 11 | } |
Program Output
A ABA ABCBA ABCDCBA ABCDEDCBA
Explanation
Each row prints ascending alphabets from 'A' up to the row index, then descending alphabets back to 'A', creating a palindromic sequence of letters per row that forms a symmetric alphabet pyramid.
