Java Alphabet Pattern 5

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=69; i>=65; 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

ABCDE
ABCD
ABC
AB
A

🧠 How the Program Works

Let's break down the logic behind the code:

The public class Demo line indicates the declaration of a public class named Demo.
public static void main(String[] args) is the entry point of the program. It's where the program execution begins. The main method takes an array of strings args as its parameter, though in this program, args is not used.
int i, j; declares two integer variables, i and j, which will be used for controlling loops.
for(i=69; i>=65; i--) starts a for loop. It initializes i with the value 69 (ASCII value of 'E'), runs the loop as long as i is greater than or equal to 65 (ASCII value of 'A'), and decrements i by 1 in each iteration.
Inside the outer loop, there is another nested for loop: for(j=65; j<=i; j++). This loop initializes j with the value 65 (ASCII value of 'A'), runs the loop as long as j is less than or equal to i, and increments j by 1 in each iteration. This loop is responsible for printing the characters.
Inside the nested loop, System.out.format("%c", j); is used to print the character represented by the ASCII value of j.
System.out.println(); is used to print a newline character, moving to the next line after printing the characters in the nested loop.
The inner loop will execute repeatedly, printing characters from 'A' to the current value of i.
After the inner loop completes, the program moves to the next iteration of the outer loop, where i is decremented by 1 and the process repeats.
This pattern continues until i is less than 65, at which point the outer loop terminates, and the program execution completes.

💯 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.
