Java Alphabet Pattern 1

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<=69; i++)
  {
   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
AB
ABC
ABCD
ABCDE

🧠 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 is a main method. This method is the entry point of the program and will be executed when the program is run.
Inside the main method, two integer variables i and j are declared. These variables will be used as loop counters.
The outer loop: for(i=65; i<=69; i++)
- This loop runs for values of i starting from 65 (which corresponds to the ASCII value of 'A') up to 69 (which corresponds to the ASCII value of 'E').
- For each value of i, the inner loop will be executed.
The inner loop: for(j=65; j<=i; j++)
- This loop runs for values of j starting from 65 (ASCII value of 'A') up to the current value of i.
- It prints the characters corresponding to the ASCII values from 'A' to the current value of i.
Inside the inner loop, System.out.format("%c", j) is used to print the character corresponding to the current value of j as per the ASCII value.
After the inner loop completes, System.out.println() is used to print a newline character, which moves the output to the next line.
The program execution moves to the next iteration of the outer loop, and the process repeats.
Once the outer loop finishes, the program ends.

💯 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.
