Java Number Pattern 26

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=5; j>=1; j--) 
   {
    if(i == j)
     System.out.print("*");
    else
     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 with the declaration of a public class named Demo.
Inside the Demo class, there is a main method declared with the public static void modifiers. This is the entry point of the program.
Two integer variables i and j are declared but not initialized.
The outer loop for(i = 1; i <= 5; i++) runs from i = 1 to i = 5 (inclusive) and controls the number of rows in the pattern.
Inside the outer loop, there is an inner loop for(j = 5; j >= 1; j--) that runs from j = 5 to j = 1 (inclusive) and controls the number of characters in each row.
Within the inner loop, there is a conditional statement:
- If i is equal to j, it prints a single asterisk (*) using System.out.print("*");. This condition generates the diagonal line of asterisks.
- If i is not equal to j, it prints the value of j using System.out.print(j);. This generates the decreasing sequence of numbers on each row.
After the inner loop completes, the program moves to the next line using System.out.println();. This creates a new line, which separates each row of characters.
The outer loop repeats this process for each row, creating a pattern where there's a diagonal line of asterisks (*), and on the other side of the diagonal, the numbers decrease from 5 to 1.
After all iterations of both loops are complete, the program exits the main method.

💯 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.
