Java Number Pattern 50

Here`s a program that prints the above number 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=i; j>1; j--)
    System.out.print(j);
   for(k=1; k<=6-i; k++)
    System.out.print(k);
   System.out.println(); 
  }
 }
}

💻 Testing the Program

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

🧠 How the Program Works

Let's break down the logic behind the code:

The class is defined as Demo.
The main method is the entry point of the program and is where the execution starts. It takes an array of strings args as its parameter.
Three integer variables i, j, and k are declared to be used as loop counters.
The outer loop for (i = 1; i <= 5; i++) runs from i = 1 to i = 5. This loop controls the number of lines in the output pattern.
Inside the outer loop, there are two nested loops:
1. The first nested loop for (j = i; j > 1; j--) prints the decreasing numbers from i down to 2. This loop is responsible for the left side of the pattern.
2. The second nested loop for (k = 1; k <= 6 - i; k++) prints the increasing numbers starting from 1 up to 6 - i. This loop is responsible for the right side of the pattern.
After both nested loops complete their iterations for the current value of i, a System.out.println(); statement is used to move to the next line, creating the newline effect.
The outer loop continues to iterate until i becomes 5, completing the generation of 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.
