Java Alphabet Pattern 16

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;
  int k = 65;
  for(i=65; i<=69; i+=2)
  {
   for(j=69; j>=65; j--)
   {
    if(j > i)
     System.out.print(" ");
    else
     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
  B C D
E F G H I

🧠 How the Program Works

Let's break down the logic behind the code:

The program defines a class named Demo.
Inside the class, there's a main method, which is the entry point of the program.
The variables i and j are declared to be used as loop counters.
The variable k is initialized with the ASCII value of 'A', which is 65.
The outer loop (for(i=65; i<=69; i+=2)) runs from 65 to 69 with a step of 2. This loop controls the rows of the pattern.
Inside the outer loop, there's an inner loop (for(j=69; j>=65; j--)) that runs from 69 to 65 in reverse order. This loop controls the columns within each row.
Inside the inner loop, there's an if-else condition:
- If the value of j (the current column) is greater than the value of i (the current row), a space is printed using System.out.print(" ").
- Otherwise (when j is less than or equal to i), a character is printed using System.out.format("%c ",k++), and the value of k is incremented.
After each row is printed using the inner loop, a newline is printed using System.out.println(); to move to the next line.
The outer loop repeats for the next row until the condition i<=69 is no longer satisfied.

💯 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.
