Java Star Pattern 3

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=1; i<=5; i++)
  {
   for(j=5; j>i; j--)
    System.out.print(" ");
   for(k=1; k<=i; 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:

The Demo class is defined with a main method, which serves as the entry point for the program.
Three integer variables, i, j, and k, are declared to control the loops and manage the pattern printing.
The outer loop (for(i=1; i<=5; i++)) iterates from i = 1 to i = 5, representing each row of the pattern. In this case, it will create a pattern with 5 rows.
Inside the outer loop, there are two inner loops:
1. The first inner loop (for(j=5; j>i; j--)) prints spaces before the asterisks. The number of spaces decreases as i increases, which creates a right-aligned pattern.
2. The second inner loop (for(k=1; k<=i; k++)) prints asterisks. The number of asterisks increases as i increases, forming the left side of the triangle.
After printing the spaces and asterisks for each row, there's a System.out.println(); statement to move to the next line, creating a new row in the pattern.

💯 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.
