Java Alphabet Pattern 18

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<=i; j++)
    System.out.format("%c", j);
   for(k=i-1; k>=65; k--)
    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
ABA
ABCBA
ABCDCBA
ABCDEDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

public class Demo: Defines a class named Demo.
public static void main(String[] args): This is the entry point of the program. It's the main function where execution begins when the program runs. The args parameter is not used in this program.
int i, j, k;: Declares three integer variables i, j, and k to be used in the loops.
for(i=65; i<=69; i++): The outer loop runs from i being initialized to 65 (ASCII value of 'A') up to 69 (ASCII value of 'E'). This loop controls the rows of the pattern.
for(j=65; j<=i; j++): The inner loop runs from j being initialized to 65 up to the current value of i. It prints characters in increasing order. The %c format specifier is used to print the character representation of the ASCII value.
for(k=i-1; k>=65; k--): Another inner loop is used to print characters in decreasing order. It starts from the value of i minus 1 (to avoid repeating the last character of the increasing sequence) and goes down to 65 (ASCII value of 'A').
System.out.println();: After both inner loops have printed characters for the current row, a newline character is printed to move to the next line for the next row.

💯 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.
