OOP and Java Basics Quiz

Encapsulation

• Refers to the bundling of data and methods (functions that operate on the data) into a single unit: an object.
• This means each object has both data (its attributes) and behavior (its methods).
• Encapsulation protects data and methods from external interference, enhancing code organization and maintainability.

Class

• A blueprint or template from which individual objects are created.
• Defines the common attributes (data) and methods (behavior) that objects of that class will share.
• It's like a blueprint for houses — the class is the plan, and each house built from that plan is an object.

Inheritance

• Enables a class to inherit properties and methods from another class, known as the parent or superclass.
• This promotes code reuse and extends functionality without having to rewrite the entire code block.
• It's like family traits — a child inherits characteristics from their parents.

Polymorphism

• The ability of a function or method to behave differently based on the context in which it is used.
• The same method can work on different types of objects with different data.
• Promotes flexibility by allowing the same code to be used in multiple ways.

Code Reusability

• One of the main advantages of Object-Oriented Programming (OOP).
• Using inheritance, programmers can reuse existing code modules to build new functions or extend existing ones.
• This significantly reduces development time and effort.
