Java Number Pattern 21

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, k, m;
  for(i=1; i<=5; i++)
  {
   System.out.print(i +" ");
   m = 4;
   k = i + m;
   for(j=1; j<i; j++)
   {
    System.out.print(k +" ");
    m--;
    k = k + m;
   }
   System.out.println();
  }
 }
}

💻 Testing the Program

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

Output

1
2 6
3 7 10
4 8 11 13 
5 9 12 14 15

🧠 How the Program Works

Let's break down the logic behind the code:

The program defines a class named Demo.
Inside the class, there's a main method which serves as the entry point of the program.
The main method declares four integer variables: i, j, k, and m.
There's an outer for loop that iterates from i=1 to i<=5.
Inside the outer loop, the program prints the value of i followed by a space using System.out.print(i +" ").
The variable m is assigned the value 4.
The variable k is assigned the value of i + m.
Inside the outer loop, there's an inner for loop with the variable j iterating from j=1 to j<i.
Inside the inner loop, the program prints the value of k followed by a space using System.out.print(k +" ").
The value of m is decremented by 1 using m--.
The value of k is updated by adding the value of m to it (k = k + m).
After the inner loop completes, the program prints a new line using System.out.println() to move to the next line.
The outer loop continues until i reaches 5, which completes the pattern.

💯 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.
