Java Alphabet Pattern 12

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

💻 Testing the Program

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

Output

AAAAA
BBBB
CCC
DD
E

🧠 How the Program Works

Let's break down the logic behind the code:

The program defines a class named Demo.
Inside the class, there is a main method, which is the entry point of the program.
Two integer variables, i and j, are declared but not initialized.
The outer loop (for loop) runs from i = 65 to i <= 69, which means it will iterate five times because ASCII value 65 corresponds to the character 'A', and 69 corresponds to the character 'E'. This outer loop controls the rows of the pattern.
Inside the outer loop, there is another loop (nested for loop) that runs from j = 69 down to j >= i. This inner loop controls the columns of the pattern. It prints the character represented by the ASCII value stored in variable i repeatedly.
The statement System.out.format("%c", i); prints the character represented by the ASCII value i.
After the inner loop completes, a newline character is printed using System.out.println();. This moves the output to the next line, creating a new row in the pattern.
The outer loop continues to the next iteration, and the value of i is incremented by 1. This will change the character being printed in each row as the ASCII value increases.
This process continues until the outer loop completes all five iterations.

💯 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.
