AP Computer Science A 100& Correct What is encapsulation in object-oriented programming? Encapsulation is the concept of bundling data (fields) and methods (functions) that operate on the data into a single unit, typically a class. It helps to protect the internal state of an object and exposes only necessary parts through public methods. What does inheritance allow you to do in Java? Inheritance allows a subclass to inherit fields and methods from a superclass. This promotes co...

Object - An instance of a class Class - Blueprint/prototype from which objects are created Inheritance - subclasses can inherit states/behaviors of superclasses interface - contract between class and outside world; when a class implements an interface, it promises to provide the behavior published by that interface package - a namespace for organizing classes & interfaces in a logical manner; makes large software projects easier to manage Encapsulation - Hiding the internal state ...
