Java Alphabet Pattern 24

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);
   for(j=65; 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

A
BAB
CBABC
DCBABCD
EDCBABCDE

🧠 How the Program Works

Let's break down the logic behind the code:

public class Demo: This line declares a public class named "Demo." In Java, every program must have a class with a main method to be executed.
public static void main(String[] args): This is the main method, which serves as the entry point for the program. It takes an array of strings as its argument but doesn't use it in this case.
Inside the main method, two integer variables i and j are declared.
The outer loop: for(i=65; i<=69; i++) - This loop iterates through values of i from 65 to 69. These values correspond to ASCII characters 'A' to 'E'.
The first inner loop: for(j=i; j>65; j--) - This loop runs from the current value of i (which starts at 'A') down to 66 ('B'). It prints characters in descending order.
The System.out.format("%c", j); statement inside the first inner loop prints the character represented by the ASCII value j.
The second inner loop: for(j=65; j<=i; j++) - This loop runs from 'A' to the current value of i. It prints characters in ascending order.
The System.out.format("%c", j); statement inside the second inner loop prints the character represented by the ASCII value j.
After the inner loops, there's a System.out.println(); statement, which moves to the next line. This creates a new line for each row of the pyramid.
The outer loop continues until i reaches 69 ('E'), and the inner loops and line break are repeated for each iteration.

💯 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.
