Java Alphabet Pattern 17

Here`s a program that prints the above alphabet pattern using Java Programming:

Demo.java

Copied

public class Demo
{
 public static void main(String[] args)
 {
  int i, j;
  for(i=65; i<=69; i++)
  {
   for(j=69; j>=65; j--)
   {
    if(i == j)
     System.out.print("*");
    else
     System.out.format("%c", j);
   }
   System.out.println();
  }
 }
}

💻 Testing the Program

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

Output

EDCB*
EDC*A
ED*BA
E*CBA
*DCBA

🧠 How the Program Works

Let's break down the logic behind the code:

The program defines a public class named Demo.
Inside the class, there's a main method, which is the entry point of the program.
Two integer variables i and j are declared to control the loops.
The outer loop (for loop) runs from i = 65 (ASCII value of 'A') to i <= 69 (ASCII value of 'E').
Inside the outer loop, there's an inner loop (for loop) that runs from j = 69 (ASCII value of 'E') to j >= 65 (ASCII value of 'A').
Within the inner loop:
- If i is equal to j, a single '*' is printed.
- If i is not equal to j, the character corresponding to the ASCII value j is printed using System.out.format("%c", j).
After the inner loop completes for a particular value of i, a newline is printed using System.out.println() to move to the next line before the next iteration of the outer loop.
The entire process continues for each value of i in the outer loop, resulting in the formation of a pattern where '*' appears diagonally from the top left to the bottom right, and other characters are printed in a descending order from 'E' to 'A'.

💯 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.
