Actual values passed to the parameters when the method is called.

A blueprint for creating objects, defining their data (attributes) and actions (methods).

Special methods used to initialise an object

The process of identifying and fixing errors or bugs in the code

The process of breaking down a complex problem into smaller, more manageable parts.

The process of creating a specific object from a class.

Collections of pre-written classes and methods that can be integrated into programs.

Last-in, First-out principle.

A variable used to pass data into a method.

Variables used in methods to receive data from the caller.
