Java Alphabet Pattern 27

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, k;
  for(i=65; i<=69; i++) 
  {
   for(j=69; j>i; j--)
    System.out.print(" ");
   for(k=65; k<=i; k++)
    System.out.format("%2c", k);
   System.out.println();
  }
 }
}

💻 Testing the Program

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

Output

    A
   A B
  A B C
 A B C D
A B C D E

🧠 How the Program Works

Let's break down the logic behind the code:

public class Demo: This line defines a Java class named "Demo."
public static void main(String[] args): This line is the entry point of the program and defines the main method. The main method is where the program execution starts when you run the program.
Inside the main method, there are three integer variables declared: i, j, and k. These variables will be used in loops to control the flow of the program.
The outer loop: for(i=65; i<=69; i++): This loop iterates from i starting at 65 (which corresponds to the ASCII value of 'A') up to 69 (which corresponds to the ASCII value of 'E'). It controls the number of rows in the pattern.
Inside the outer loop, there are two nested loops:
- The first nested loop: for(j=69; j>i; j--): This loop is responsible for printing spaces before the characters on each row. It starts with j at 69 (which corresponds to the ASCII value of 'E') and decrements j until it becomes greater than i. This creates the indentation effect.
- The second nested loop: for(k=65; k<=i; k++): This loop is responsible for printing the characters in each row. It starts with k at 65 (which corresponds to the ASCII value of 'A') and increments k until it reaches the current value of i. The System.out.format("%2c", k) statement is used to format the character output, ensuring that each character is printed with two spaces, creating a neat pattern.
After the inner loops, System.out.println(); is used to move to the next line, creating a new row in the pattern.
The program continues to loop until i reaches 69, and the pattern is printed row by 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.
