Java Alphabet Pattern 28

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;
  int k = 69;
  for(i=k; i>=65; i--)
  {
   for(j=k; j>=65; j--)  
   {
    if(j > i)
     System.out.format("%c ", j);
    else
     System.out.format("%c ", i);
   }
   for(j=66; j<=k; j++)
   {
    if(j > i)
     System.out.format("%c ", j);
    else
     System.out.format("%c ", i);
   }
   System.out.println();
  }
 }
}

💻 Testing the Program

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

Output

E E E E E E E E E
E D D D D D D D E
E D C C C C C D E
E D C B B B C D E
E D C B A B C D E

🧠 How the Program Works

Let's break down the logic behind the code:

public class Demo: This line defines a class named Demo.
public static void main(String[] args): This line is the main method, the entry point for the program's execution. It takes an array of strings as arguments, although these arguments are not used in this program.
Inside the main method:
1. int i, j;: Declares two integer variables i and j without initializing them.
2. int k = 69;: Initializes an integer variable k with the value 69. This value corresponds to the ASCII code of the character 'E'.
3. for(i=k; i>=65; i--): This is the outer loop, which iterates from k (69) down to 65 (the ASCII code for 'A'). It controls the rows of the inverted pyramid.
4. for(j=k; j>=65; j--): This is the inner loop within the outer loop. It also iterates from k down to 65, controlling the characters printed in each row.
  - Inside this inner loop, there is an if condition that checks if j is greater than i. If it is, it prints the character represented by the ASCII value of j. Otherwise, it prints the character represented by the ASCII value of i.
5. After the inner loop, there's another loop: for(j=66; j<=k; j++). This loop iterates from 66 (ASCII code for 'B') up to k (69).
  - Inside this inner loop, there's another if condition that checks if j is greater than i. If it is, it prints the character represented by the ASCII value of j. Otherwise, it prints the character represented by the ASCII value of i.
6. System.out.println();: This line prints a newline character to move to the next row after completing both inner loops for the current row.
The outer loop continues until i reaches 65, at which point the program exits, and the inverted pyramid pattern is printed.

💯 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.
