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.
