Java Alphabet Pattern 31

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(i == j)
     System.out.format("%c", j);
    else
     System.out.print(" ");
   }
   for(k=68; k>=65; k--)
   {
    if(i == k)
     System.out.format("%c", k);
    else
     System.out.print(" ");
   }
   System.out.println();
  }
 }
}

💻 Testing the Program

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

Output

A       A
 B     B
  C   C
   D D
    E

🧠 How the Program Works

Let's break down the logic behind the code:

The program defines a public class named Demo.
Inside the class, there's a public static void main(String[] args) method, which is the entry point of the program.
Inside the main method, three integer variables i, j, and k are declared.
The program enters a nested loop structure with two for loops. The outer loop runs from i = 65 to i <= 69, and the inner loop runs from j = 65 to j <= 69.
Inside the innermost loop, there's an if statement that checks if i is equal to j. If i is equal to j, it prints the character represented by the ASCII value of j using System.out.format("%c", j);. Otherwise, it prints a space using System.out.print(" ");.
After the inner loop finishes executing, there is another nested loop structure. This time, it's for variable k, which runs from k = 68 down to k >= 65.
Inside the innermost loop for k, there's another if statement that checks if i is equal to k. If i is equal to k, it prints the character represented by the ASCII value of k using System.out.format("%c", k);. Otherwise, it prints a space using System.out.print(" ");.
After both inner loops complete, a newline character is printed using System.out.println() to move to the next row of the pattern.
The outer loop repeats, and the process continues until i is no longer less than or equal to 69.

💯 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.
