Java Alphabet Pattern 13

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++) 
  {
   for(j=65; j<=i; j++)
    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 J
K L M N O

🧠 How the Program Works

Let's break down the logic behind the code:

public class Demo: This line defines the start of the class named Demo.
public static void main(String[] args): This line is the main method declaration, the entry point for the program's execution. It takes an array of strings as arguments.
int i, j;: Declares two integer variables i and j which will be used as loop counters.
int k = 65;: Initializes an integer variable k with the ASCII value of the character 'A'.
for(i=65; i<=69; i++): The outer loop runs from i = 65 (ASCII value of 'A') to i <= 69 (ASCII value of 'E').
Inside the outer loop, there's another loop, for(j=65; j<=i; j++), which iterates from j = 65 to j <= i. This inner loop is responsible for printing characters within a row.
System.out.format("%c ", k++);: Within the inner loop, this line prints the character represented by the ASCII value stored in k, using the %c format specifier. Then, it increments k to represent the next character in the ASCII sequence.
System.out.println();: After the inner loop completes for a row, this line moves the cursor to the next line to start the next row.
The program execution continues until the outer loop completes for all rows.

💯 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.
