Java Number Pattern 34

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=0; i<=5; i++)
  {
   for(j=0; j<=i; j++)
    System.out.print((i+j) +" ");
   System.out.println();
  }
 }
}

💻 Testing the Program

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

Output

0
1 2 
2 3 4
3 4 5 6
4 5 6 7 8
5 6 7 8 9 10

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts with the declaration of a Java class named Demo.
Inside the class, there's the main method. This is the entry point of the program, where the execution begins when the program is run.
Two integer variables i and j are declared. These variables will be used for controlling the loops.
The outer loop: for(i=0; i<=5; i++) - This loop will iterate i from 0 to 5 (inclusive).
Inside the outer loop, there's another loop, the inner loop: for(j=0; j<=i; j++). This loop will iterate j from 0 to the current value of i (inclusive).
Inside the inner loop, there's a statement: System.out.print((i+j) + " ");. This statement prints the sum of i and j followed by a space. The purpose of this line is to print a pattern of numbers in each row.
After the inner loop finishes, there's a System.out.println(); statement. This prints a newline character, moving the printing to the next line. This is used to start a new line after each row of numbers is printed.
The outer loop iterates, and the inner loop executes according to the current value of i. This creates a pattern where each row of numbers has a different number of elements, starting from 1 and increasing by one element in each subsequent row.
The program will continue this pattern until the outer loop completes its iterations.

💯 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.
