Number Grid
This program prints a 3x3 number grid using nested for loop.
Problem Statement
Write a Java program that prints a 3x3 grid of numbers using nested for loop.
Source Code
| 1 | public class NumberGrid { |
| 2 | public static void main(String[] args) { |
| 3 | for(int i=1; i<=3; i++) { |
| 4 | for(int j=1; j<=3; j++) { |
| 5 | System.out.print(j + " "); |
| 6 | } |
| 7 | System.out.println(); |
| 8 | } |
| 9 | } |
| 10 | } |
Program Output
1 2 3 1 2 3 1 2 3
Explanation
The outer loop controls rows, and the inner loop prints numbers 1 to 3 in each row. This demonstrates how nested loops can generate grids. Shows how nested for loops can print number grids.
