Java Number Pattern 15

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>=1; j--)
    System.out.print(j % 2);
   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 program defines a class named Demo.
Inside the class, there's a main method declared with the standard signature public static void main(String[] args). This is the entry point of the program.
The variables i and j of type int are declared but not initialized.
The outer loop runs from i = 1 to i <= 5. This loop controls the number of rows in the pattern.
Inside the outer loop, there's an inner loop. The inner loop runs from j = i to j >= 1. This loop controls the number of binary digits to be printed in each row.
Inside the inner loop, the program prints the value of j % 2. The expression j % 2 calculates the remainder when j is divided by 2, effectively producing alternating 0 and 1 values.
After printing the binary digit, there's no space or newline character, so the digits are printed side by side.
After the inner loop completes, the program uses System.out.println(); to move to the next line, starting a new row for the pattern.
The outer loop continues to execute for each value of i, creating a row of alternating binary digits for each value.
Once the outer loop completes, the program terminates.

💯 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.
