Java Number Pattern 22

Here`s a program that prints the above number pattern using Java Programming:

Demo.java

Copied

public class Demo
{
 public static void main(String[] args)
 {
  int i, j;
  for(i=1; i<=9; i+=2)
  {
   for(j=1; j<=i; j++)
    System.out.print(j);
   System.out.println();
  } 
 } 
}

💻 Testing the Program

When you run the above program, it will print the following output:

🧠 How the Program Works

Let's break down the logic behind the code:

Class Declaration: The program starts by declaring a public class named Demo.
Main Method: The program contains a main method which is the entry point for execution in a Java program. It takes an array of strings (args) as its parameter.
Variable Declaration: Inside the main method, two integer variables i and j are declared without any initial values.
Outer Loop (for loop): The outer loop is a for loop that initializes i to 1. The loop continues as long as i is less than or equal to 9. In each iteration, i is incremented by 2 (i += 2).
Inner Loop (for loop): Inside the outer loop, there's another for loop that initializes j to 1. The loop continues as long as j is less than or equal to i.
Print Numbers: Within the inner loop, the program prints the value of j using System.out.print(j). This prints the numbers from 1 to i without spaces.
New Line: After the inner loop completes (once j is greater than i), the program prints a newline character using System.out.println(). This moves the cursor to the next line, creating a new line for the next set of numbers.
Repeat: The outer loop continues to the next iteration with an updated value of i, repeating the process of printing numbers and new lines.

💯 Tips for Enhancement:

Explore the versatility of this pattern by adjusting its parameters. Whether you increase or decrease the size, tweak the spacing, or modify the characters used, each change opens up a world of possibilities, allowing you to customize and create your unique visual effects.
