/*
- We defined a class named "Extra".
- Inside the "Main" Class we define the main method which is an entry point of the program
- We call the "PrintWelcomeMessage" method which prints a welcome message to the console.
- The "printWelcomeMessage" method is declared with a return type void, indicating that it doesn't return anything.
- The method doesn't have any parameters.
- Inside the method, we use System.out.println to print the welcome message.

/*
This demonstrates how to define and call a method in Java that doesn't return anything and doesn't have any parameters.
You can use such methods for performing tasks that don't require input parameters or returning values.

// YOU CAN DECLARE A FUNCTION BEFORE CALLING IT OR YOU CAN CALL THE FUNCTION BEFORE DECLARING IT. BOTH WILL WORK
