Java Number Pattern 3

Here`s a program that prints the above number pattern using JavaScript Programming:

Demo.java

Copied

public class Demo
{
 public static void main(String[] args)
 {
  int i, j;
  for(i=5; i>=1; i--)
  {
   for(j=i; j>=1; j--)
    System.out.print(j);
   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 by defining a class named Demo.
Inside the class, there is a public static void main(String[] args) method. This is the entry point of the program, and it's where the execution begins.
Two integer variables, i and j, are declared to be used as loop counters.
The outer for loop is used to iterate through the values of i from 5 down to 1. The loop header for(i=5; i>=1; i--) initializes i to 5, continues as long as i is greater than or equal to 1, and decrements i after each iteration.
Inside the outer loop, there is an inner for loop. This loop is used to iterate through the values of j starting from the current value of i down to 1. The loop header for(j=i; j>=1; j--) initializes j to the current value of i, continues as long as j is greater than or equal to 1, and decrements j after each iteration.
Within the inner loop, the statement System.out.print(j) prints the value of j without a newline. This effectively prints the numbers from the current value of i down to 1 on the same line.
After the inner loop completes, the statement System.out.println() is executed to print a newline character, causing the next set of numbers to be printed on a new line.
The outer loop repeats this process for each decreasing value of i, resulting in a pattern of decreasing numbers being printed.
Once the loops complete their execution, the main method ends.

💯 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.
