Concentric Alphabet Square
This program prints concentric squares using alphabets.
Problem Statement
Write a Java program that prints concentric alphabet squares in a 5x5 grid.
Source Code
| 1 | public class ConcentricAlphabetSquare { |
| 2 | public static void main(String[] args) { |
| 3 | int n = 5; |
| 4 | for(int i=0; i<n; i++) { |
| 5 | for(int j=0; j<n; j++) { |
| 6 | int min = Math.min(Math.min(i, j), Math.min(n-1-i, n-1-j)); |
| 7 | char ch = (char)('A' + min); |
| 8 | System.out.print(ch + " "); |
| 9 | } |
| 10 | System.out.println(); |
| 11 | } |
| 12 | } |
| 13 | } |
Program Output
A A A A A A B B B A A B C B A A B B B A A A A A A
Explanation
The distance min from the border is computed as before, and a character 'A'+min is derived from it, so concentric layers are printed with alphabets instead of numbers, demonstrating mathematical logic combined with character arithmetic.
