Java Number Pattern 16

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=1; j<=i; j++)
    System.out.print(j % 2);
   System.out.println();
  }
 }
}

💻 Testing the Program

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

Output

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts by defining a class named Demo.
Inside the class, there's a main method declared with the signature: public static void main(String[] args). 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 at the beginning of the main method. These variables will be used in the loops to control the flow of the program.
The outer for loop runs from i = 1 to i <= 5. This loop is responsible for controlling the number of rows in the output pattern.
Inside the outer loop, there's an inner for loop that runs from j = 1 to j <= i. This loop controls the number of columns in each row of the output pattern.
Within the inner loop, there's a single statement: System.out.print(j % 2). This statement prints the value of j % 2 to the console without moving to the next line. The expression j % 2 calculates the remainder when j is divided by 2, effectively generating a repeating pattern of 0 and 1.
After printing the numbers in the inner loop, the program executes System.out.println(). This is used to move to the next line, effectively creating a new row in the output pattern.
The outer loop continues to the next iteration, and the value of i increases by 1.
Steps 5-7 are repeated for each iteration of the outer loop, creating a triangular pattern of alternating 0s and 1s.
Once the outer loop completes all five iterations (from i = 1 to i = 5), the program finishes executing.

💯 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.
