Java Alphabet Pattern 2

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=69; i>=65; i--) 
  {
   for(j=69; j>=i; j--) 
    System.out.format("%c", j);
   System.out.println(); 
  }
 }
}

💻 Testing the Program

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

Output

E
ED
EDC
EDCB
EDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

The program defines a class named Demo.
Inside the class, there's a main method declared. This method is the entry point for the program's execution.
Two integer variables i and j are declared but not initialized yet. These variables will be used in the loops to control the rows and columns of characters.
The outer loop for(i=69; i>=65; i--) runs from i initialized with the ASCII value of 'E' down to the ASCII value of 'A'. It iterates five times (E, D, C, B, A).
Inside the outer loop, there's an inner loop for(j=69; j>=i; j--). This loop also runs from the ASCII value of 'E' down to the current value of i. The purpose of this loop is to print characters in descending order.
Within the inner loop, System.out.format("%c", j); prints the character corresponding to the ASCII value stored in j. The %c format specifier is used to represent a character.
After the inner loop, System.out.println(); is used to print a newline character, which moves the printing to the next line before starting the next iteration of the outer loop.
As the outer loop iterates, the inner loop prints characters in decreasing order based on the value of i. So, for each iteration of the outer loop, the program prints a row of characters in reverse order.
After all iterations of the outer and inner loops, the program has printed a pattern of characters that forms a triangle-like pattern, where each row has characters decreasing from 'E' down to the respective character based on the current iteration of the outer loop.

💯 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.
