Java Alphabet Pattern 7

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=i; j>=65; 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

EDCBA
DCBA
CBA
BA
A

🧠 How the Program Works

Let's break down the logic behind the code:

public class Demo: Defines a public class named Demo.
public static void main(String[] args): This is the main method where the program execution starts. It takes an array of strings (args) as its parameter, although in this program, the args array isn't used.
int i, j;: Declares two integer variables i and j to be used in the loops.
for(i = 69; i >= 65; i--): This outer loop runs from i = 69 (ASCII value of 'E') down to i = 65 (ASCII value of 'A') with a decrement of 1 in each iteration. This loop controls the rows of the triangle.
for(j = i; j >= 65; j--): This inner loop runs from the current value of i down to j = 65 (ASCII value of 'A') with a decrement of 1 in each iteration. This loop controls the columns of characters in each row.
System.out.format("%c", j);: Inside the inner loop, this line prints the character corresponding to the current value of j. Since j has been initialized to the value of i, this prints the uppercase English letters in descending order.
System.out.println();: After the inner loop completes, this line is executed to print a newline character, moving the printing to the next row in the triangle.
The inner loop continues executing until j reaches the value of 65 (ASCII value of 'A'), and the characters are printed in a row.
Once the inner loop completes, the program moves to the next iteration of the outer loop, and the value of i decreases, causing the next row to have one less character.
The process repeats until the outer loop completes and i reaches the value of 65 (ASCII value of 'A'), thus creating the pattern of a right-angled triangle with descending characters.

💯 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.
