Chapter 5: Methods and Parameter Passing in Java
Methods are essential in programming, allowing for the organization of code into manageable sections. Parameters and return types add flexibility to method definitions, enabling a clear flow of data. In Java, methods use call by value for argument passing, and method overloading gives the option to define multiple methods with the same name but varying parameters. Additionally, static methods highlight the distinction between class-level functionalities and instance-based behaviors.

What we have learnt
- Methods allow division of programs into manageable parts.
- Parameters and return types enhance method flexibility.
- Java uses call by value instead of reference.
- Method overloading permits multiple methods sharing the same name but differing in parameters.
- Static methods are associated with the class rather than objects.
Key Concepts
- -- Method
- A block of code designed to perform a specific task, promoting code organization and reuse.
- -- Parameter
- A variable used in a method declaration to accept input values.
- -- Argument
- The actual value passed to a method when it is called.
- -- Method Overloading
- The ability to create multiple methods with the same name within the same class, differentiated by parameter lists.
- -- Static Method
- A method that belongs to the class rather than instances of the class and can be called without creating an object.
