Numeric-Alphabet Star Mosaic
This program prints a mosaic alternating numbers, alphabets, and stars.
Problem Statement
Write a Java program that prints a 6x6 mosaic alternating numbers, alphabets, and stars.
Source Code
| 1 | public class NumericAlphabetStarMosaic { |
| 2 | public static void main(String[] args) { |
| 3 | int n = 6, num=1; |
| 4 | char ch='A'; |
| 5 | for(int i=0; i<n; i++) { |
| 6 | for(int j=0; j<n; j++) { |
| 7 | if((i+j)%3==0) System.out.print(num++ + " "); |
| 8 | else if((i+j)%3==1) { |
| 9 | System.out.print(ch + " "); |
| 10 | ch++; |
| 11 | if(ch>'Z') ch='A'; |
| 12 | } else System.out.print("* "); |
| 13 | } |
| 14 | System.out.println(); |
| 15 | } |
| 16 | } |
| 17 | } |
Program Output
1 A * 4 B * * 7 C * 10 D E * 13 F * 16 * 19 G * 22 H I * 25 J * 28 * 31 K * 34 L
Explanation
The value (i+j)%3 cycles through three states, printing a number, an alphabet, or a star respectively, so the grid cycles through three different symbol types in a repeating diagonal-like mosaic.
