Numeric-Alphabet Star Grid

This program prints a grid alternating numbers, alphabets, and stars.

Problem Statement

Write a Java program that prints a 5x5 grid alternating numbers, alphabets, and stars.

Source Code

1 public class NumericAlphabetStarGrid {
2 public static void main(String[] args) {
3 int n = 5, 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 
E * 13 F * 
* 19 G * 22 
I * 25 J * 

Explanation

The same three-way cyclic condition (i+j)%3 as before is applied on a smaller 5x5 grid, cycling through numbers, alphabets, and stars to build a smaller hybrid mosaic grid.
