Java Alphabet Pattern 14

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;
  for(i=65; i<=74; i+=2)
  {
   for(j=65; j<=i; j++)
    System.out.format("%c", j);
   System.out.println();
  }
 }
}

💻 Testing the Program

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

Output

A
ABC
ABCDE
ABCDEFG
ABCDEFGHI

🧠 How the Program Works

Let's break down the logic behind the code:

public class Demo: This defines a class named Demo.
public static void main(String[] args): This is the main method where the program execution starts. It takes an array of strings args as a parameter, which can be used to pass command-line arguments to the program.
int i, j;: Declares two integer variables i and j.
for (i = 65; i <= 74; i += 2): This is the outer loop that iterates over the values of i starting from 65 and going up to 74 (inclusive) with a step of 2 in each iteration.
for (j = 65; j <= i; j++): This is the inner loop that iterates over the values of j starting from 65 and going up to the current value of i in the outer loop.
System.out.format("%c", j);: This line prints the character represented by the ASCII value of j. Since j is initialized to 65, which corresponds to the ASCII value of 'A', it will print 'A' in the first iteration of the inner loop, 'AB' in the second iteration, 'ABC' in the third, and so on.
System.out.println();: This line prints a newline character to move to the next line after printing each sequence of characters in the inner loop.
The outer loop continues to increment i by 2 in each iteration and runs the inner loop accordingly, creating a pattern of characters. The ASCII values of characters increase with each iteration, forming a triangle-like pattern of characters.

💯 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.
