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...

Distributed What are the fundamental principles of OOP? ~ 1. Inheritance 2. Abstraction 3. Polymorphism 4. Encapsulation What is Inheritance in Java? ~ Inheritance is one of the key principles of OOP. Through Inheritance, one class can inherit the properties of another class. The class from which properties are inherited is called a...

Encapsulation - a fundamental principle of object-oriented programming, whereby the internal components of a class are hidden from external classes and are only accessed via getter / setter methods. Why use encapsulation? - so that you can change the internal implementation of a class without affecting other classes. instantiation - Process of creating an object, an instance of a class; creates space in memory for the new object and binds a name for the object with the object's data in me...

OOAD EXAM REVIEW QUESTIONS AND ANSWERS, GRADED A+/ VERIFIED/ Inheritance should be used more than composition to create more flexible classes - -False - inheritance requires more testing to ensure desired behavior.
