Java Alphabet Pattern 26

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=i; j<=69; j++)
    System.out.format("%c", j);
   for(k=i; k>65; k--)
    System.out.format("%c", k-1);
   System.out.println(); 
  } 
 }
}

💻 Testing the Program

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

Output

ABCDE
BCDEA
CDEBA
DECBA
EDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts by defining a class named "Demo."
Inside the class, there is 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. These variables will be used as loop counters.
The outermost loop is a for loop with the variable i initialized to 65. This loop runs as long as i is less than or equal to 69 and increments i by 1 in each iteration.
Inside the outer loop, there are two nested for loops. These nested loops are responsible for printing the characters in each row of the pattern.
1. The first inner loop (for(j=i; j<=69; j++)) starts with j equal to the current value of i and continues as long as j is less than or equal to 69. It increments j by 1 in each iteration. This loop is responsible for printing characters from the current value of i to 69.
2. The second inner loop (for(k=i; k>65; k--)) starts with k equal to the current value of i and continues as long as k is greater than 65. It decrements k by 1 in each iteration. This loop is responsible for printing characters from the current value of i down to 66 ('A' - 1).
3. Inside both inner loops, System.out.format("%c", ...) is used to print the character represented by the current value of j or k.
After both inner loops complete, there is a System.out.println() statement to print a newline character. This moves to the next row of the pattern.
The outer loop continues until i reaches 70, at which point it terminates.

💯 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.
