Welcome to Module 8: Methods in Java! 📝 In this module, we'll dive into the world of methods, also known as functions. Methods are essential building blocks of any program, allowing you to break down your code into smaller, reusable pieces. By the end of this module, you'll have a solid understanding of how to create and use methods in Java to create efficient, organized, and modular programs. 🌟

Method Signature and Parameters:
The method signature includes the method name and parameter list. Parameters allow you to pass data into the method.
Calling Methods:
You can call a method by using its name along with the appropriate arguments. The method executes its code block and can return a value.
Method Overloading:
Java allows you to define multiple methods with the same name but different parameter lists. This is called method overloading.
Return Statement:
Methods can return values using the return statement. The return type in the method signature indicates the type of value the method returns.
Void Methods:
Methods that don't return a value are declared with the void return type.
Passing Parameters:
Parameters can be passed by value or by reference (for objects). Understanding how parameters are passed is crucial for effective method usage.
Stay tuned for the upcoming modules, where we'll build upon this knowledge and delve into more advanced programming concepts. Happy coding! 🚀👩💻
