Java Alphabet Pattern 20

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=69; j>=65; j--) 
   {
    if(j > i)
     System.out.print(" ");
    else
     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
   BA
  CBA
 DCBA
EDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

The program defines a class named Demo.
The main method is the entry point of the program and it takes an array of strings (args) as input.
The integer variables i and j are declared to be used as loop counters.
The outer loop (for (i = 65; i <= 69; i++)) runs for i values ranging from 65 to 69 (ASCII values for 'A' to 'E', respectively).
Inside the outer loop, there is an inner loop (for (j = 69; j >= 65; j--)) that runs for j values ranging from 69 to 65.
In each iteration of the inner loop, there's a conditional statement:
- If j is greater than the current i value, a space is printed.
- If not, the character corresponding to the ASCII value of j is printed using System.out.format("%c", j).
After each iteration of the inner loop, a new line is printed to move to the next line for the next row of characters.
The pattern forms a right-angled triangle with decreasing characters on each 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.
