Java Number Pattern 12

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++)
    System.out.print(i);
   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 starts with the declaration of a Java class named Demo.
Inside the class, there's a public static void main(String[] args) method. This is the entry point of the program. It's the method that gets executed when you run the program.
Two integer variables, i and j, are declared without any initial values.
The outer loop is a for loop with the initialization expression i=1, the condition i<=5, and the increment expression i++. This loop runs from i=1 to i=5.
Inside the outer loop, there's another nested for loop. The initialization expression is j=i, which means j starts with the value of i in each iteration of the outer loop. The condition is j<=5, which means the inner loop runs as long as j is less than or equal to 5.
Inside the nested loop, there's a System.out.print(i) statement. This prints the value of i without moving to a new line.
After the inner loop completes, there's a System.out.println() statement. This prints a newline character, which moves the cursor to the next line.
The outer loop continues to its next iteration, and i is incremented by 1.
Steps 5-8 are repeated until the outer loop finishes running for all values of i from 1 to 5.

💯 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.
