Java Number Pattern 2

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<=5; i++)
  {
   for(j=i; j<=5; 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:

We start with the declaration of a Java class named Demo.
The public static void main(String[] args) method is the entry point of the program. This is where the execution of the program begins. args is an array of command-line arguments that can be passed to the program.
Inside the main method, two integer variables i and j are declared. These variables will be used as loop counters.
The outer loop is a for loop that iterates over the values of i from 1 to 5 (inclusive). The loop header for(i=1; i<=5; i++) initializes i to 1, executes the loop body as long as i is less than or equal to 5, and increments i by 1 in each iteration.
Inside the outer loop, there's an inner loop, also a for loop, with the header for(j=i; j<=5; j++). This loop initializes j to the value of i, executes the loop body as long as j is less than or equal to 5, and increments j by 1 in each iteration. This inner loop effectively prints the values of j starting from i up to 5.
Inside the inner loop, the statement System.out.print(j); prints the value of j without moving to the next line.
After the inner loop completes, the statement System.out.println(); is executed. This moves the cursor to the next line, effectively creating a new line.
The outer loop then continues to the next iteration, and the process repeats until i becomes greater than 5.

💯 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.
