Java Number Pattern 19

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;
  for(i=5; i>=1; i--)
  {
   for(j=i; j<=5; j++)
    System.out.print(j + " ");
   for(j=1; j<i; j++)
    System.out.print(5 + " ");
   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 program defines a class named Demo.
Inside the class, there's a public static void main(String[] args) method. This is the entry point of the program. The program execution starts here.
Two integer variables, i and j, are declared. These will be used in the loops for iteration.
There's an outer for loop with the condition i=5; i>=1; i--. This loop iterates from i=5 down to i=1. It controls the number of rows in the output pattern.
Inside the outer loop, there are two nested for loops and a System.out.println() statement.
The first nested for loop has the condition j=i; j<=5; j++. It iterates from the current value of i to 5. This loop is responsible for printing the values in increasing order.
Inside this loop, System.out.print(j + " ") prints the current value of j, followed by a space.
The second nested for loop follows with the condition j=1; j<i; j++. It iterates from j=1 up to (but not including) the current value of i. This loop is responsible for printing the value 5 in case of the decreasing part of the pattern.
Inside this loop, System.out.print(5 + " ") prints the value 5, followed by a space.
After both nested for loops, a System.out.println() statement is executed to move the cursor to the next line, creating a new row in the output pattern.
The outer for loop continues to the next iteration, and steps 6-10 are repeated for the next value of i.
This process continues until i becomes less than 1, which ends the outer loop.

💯 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.
