Java Number Pattern 40

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++)
   {
    if(i%2 ==  0)
     System.out.print("0");
    else
     System.out.print("1");
   }
   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:

The public class Demo line declares the class named Demo.
The public static void main(String[] args) method is the entry point of the program, where the execution begins. It takes an array of strings (args) as input.
Inside the main method, two integer variables i and j are declared but not initialized.
The outer loop for(i=1; i<=5; i++) iterates over the values of i from 1 to 5 (both inclusive).
Inside the outer loop, there's another loop for(j=i; j<=5; j++) that iterates from the current value of i to 5.
The if(i%2 == 0) condition checks if i is an even number.
If i is even, it enters the if block and prints "0" using System.out.print("0");.
If i is odd, it enters the else block and prints "1" using System.out.print("1");.
After the inner loop finishes, System.out.println(); is used to print a newline character, moving to the next line for the next row of the pattern.
The outer loop continues to the next iteration with an incremented value of i, and the inner loop executes again to print the pattern.
This process continues until the outer loop completes all iterations (i.e., i reaches 5), and the pattern is fully printed.

💯 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.
