Java Alphabet Pattern 4

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=i; j>=65; 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

A
BA
CBA
DCBA
EDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts with defining a class named Demo.
Inside the Demo class, there's a main method, which is the entry point of the program.
The int i, j; line declares two integer variables i and j.
The outer loop for (i = 65; i <= 69; i++) runs from 65 to 69 (inclusive), which corresponds to the ASCII values of 'A' to 'E'.
The outer loop for (i = 65; i <= 69; i++) runs from 65 to 69 (inclusive), which corresponds to the ASCII values of 'A' to 'E'.
Inside the outer loop, there's an inner loop for (j = i; j >= 65; j--). This inner loop starts with the value of i and decrements j until it reaches 65.
In each iteration of the inner loop, the program uses System.out.format("%c", j); to print the character represented by the ASCII value j.
After the inner loop, System.out.println(); is used to print a newline character, moving the output to the next line for the next iteration of the outer loop.
This pattern of nested loops creates the desired character pattern.
After the entire process is repeated for each value of i, the program output will match the pattern shown above.

💯 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.
