Java Alphabet Pattern 9

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", i);
   System.out.println();
  }
 }
}

💻 Testing the Program

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

Output

A
BB
CCC
DDDD
EEEEE

🧠 How the Program Works

Let's break down the logic behind the code:

public class Demo: The program defines a class named Demo.
public static void main(String[] args): This is the entry point of the program. The main method is where the execution of the program begins. It takes an array of strings args as a parameter.
int i, j;: Declare two integer variables i and j to be used as loop counters.
for(i=65; i<=69; i++): This is the outer loop. It iterates from the ASCII value 65 ('A') to the ASCII value 69 ('E').
for(j=65; j<=i; j++): This is the inner loop. It iterates from the ASCII value 65 ('A') to the current value of i. This loop is responsible for printing the same character multiple times.
System.out.format("%c", i);: Inside the inner loop, this line prints the character represented by the ASCII value i. Since i is incremented in the outer loop, the character being printed changes with each iteration of the outer loop.
System.out.println();: This line is responsible for printing a newline character, which moves the printing to the next line after each row of characters is printed.
The nested loops and print statements together create the pattern of characters in the form of a triangle. The number of characters in each row increases as the outer loop iterates.

💯 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.
