Java Star Pattern 6

Here`s a program that prints the above star pattern using Java Programming:

Demo.java

Copied

public class Demo
{
 public static void main(String[] args)
 {
  int i, j, k;
  for(i=5; i>=1; i--)
  {
   for(j=i; j<5; j++)
    System.out.print(" ");
   for(k=i*2; k>1; k--)
    System.out.print("*");
   System.out.println();
  }
 }
}

💻 Testing the Program

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

Output

*********
 *******
  *****
   ***
    *

🧠 How the Program Works

Let's break down the logic behind the code:

public class Demo: This line declares a class named Demo which contains the main method where the program starts its execution.
public static void main(String[] args): This is the main method where the program execution begins. It takes an array of strings as arguments (args), although in this program, args is not used.
Inside the main method, three integer variables are declared: i, j, and k without initialization.
for(i=5; i>=1; i--): This is an outer loop that iterates from i=5 to i=1. It decrements i by 1 in each iteration. This loop controls the number of rows in the pattern.
for(j=i; j<5; j++): This is an inner loop that iterates from the current value of i to j=4. It prints spaces (" ") in each iteration, effectively creating leading spaces for each row.
for(k=i*2; k>1; k--): This is another inner loop that iterates from k equals to i*2 down to k=1. It prints asterisks (*) in each iteration, effectively creating a sequence of asterisks.
System.out.println();: This line is used to print a newline character after the inner loops complete. This moves the output to the next line, starting a new row in the pattern.
After both inner loops complete, the program prints a newline character, effectively creating a new row in the pattern.
The outer loop continues until i reaches 1, and the pattern is built row by row with decreasing numbers of spaces and increasing numbers of asterisks.

💯 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.
