Java Alphabet Pattern 19

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

💻 Testing the Program

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

Output

A        A
AB      BA
ABC    CBA
ABCD  DCBA
ABCDEEDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

The class Demo is defined.
Inside the main method, three integer variables i, j, and k are declared to be used as loop counters.
The outermost for loop runs from i=65 to i<=69. This loop controls the rows of the pyramid.
Inside the outer loop, the first nested for loop (with j) is used to print the left half of the pyramid. It runs from j=65 to j<=69.
The innermost if-else statement in the j loop checks whether the current value of j is less than or equal to the current value of i. If true, it prints the character represented by the ASCII value of j. Otherwise, it prints a space.
After printing the left half of the pyramid, a second nested for loop (with k) is used to print the right half of the pyramid. It runs from k=69 (ASCII value of 'E') to k>=65 (ASCII value of 'A').
The innermost if-else statement in the k loop checks whether the current value of k is greater than the current value of i. If true, it prints a space. Otherwise, it prints the character represented by the ASCII value of k.
After completing the j and k loops, a newline character is printed using System.out.println() to move to the next line for the next row of the pyramid.
The outer loop repeats the process for each row, resulting in the entire pyramid being 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.
