Object-Oriented Programming Concepts Quiz

Providing a specific implementation of a method that is already defined in the superclass. = Method Overriding A class that cannot be instantiated and may have abstract methods. = Abstract Class A class that can be instantiated and provides concrete implementations for all abstract methods inherited from its abstract superclass. = Concrete Class A special method in a class that is called when an object is instantiated and is used to initialize the object's state. = Constructor

Methods used to retrieve (get) and modify (set) the values of private instance variables in a class. = Getter and Setter Methods A variable defined in a class that represents the state of an object and has its own copy for each object. = Instance Variable A variable or method that belongs to the class rather than to instances of the class and is shared among all instances. = Static Variable/Method A fundamental concept in Object-Oriented Programming (OOP) that allows a class to inherit properties and behaviors from another class. = Inheritance

A fundamental concept in Object-Oriented Programming (OOP) that refers to the ability of objects to take on multiple forms. = Polymorphism The ability of a class to have multiple methods with the same name but different parameters, determined at compile time based on the method signature. = Compile-Time Polymorphism (Method Overloading) The ability of a subclass to provide a specific implementation for a method that is already defined in its superclass, determined at runtime based on the type of the object. = Runtime Polymorphism (Method Overriding) A keyword used in Java to indicate that a class is inheriting from another class. = extends

Class = A blueprint or template for creating objects. It defines the properties (attributes) and behaviors (methods) that objects of the class will have. Object = An instance of a class. Objects represent real-world entities and encapsulate data and behavior. Inheritance = A mechanism that allows a class (subclass or child class) to inherit properties and behaviors from another class (superclass or parent class). It promotes code reuse and establishes a relationship between classes. Encapsulation = The bundling of data (attributes) and methods that operate on that data within a single unit (class). It restricts access to some components, preventing accidental modification of data.

Polymorphism = The ability of objects of different types to be treated as objects of a common type. It includes compile-time polymorphism (method overloading) and runtime polymorphism (method overriding). Abstraction = The process of simplifying complex systems by modeling classes based on the essential properties and behaviors they possess. Abstract classes and interfaces are used to achieve abstraction. Interface = A collection of abstract methods. It defines a contract for classes that implement it, ensuring that those classes provide specific functionalities. Method Overloading = Having multiple methods with the same name in a class, but with different parameter types or a different number of parameters.
