“Abstract class is a class definition that is not fully implemented; one or more class methods remain undefined with the result that no objects can be instantiated from the class.”
Java
In C++
Abstract class in C++ is “a class defining an interface only; used as a base class. Declaring a member function pure virtual makes its class abstract and prevents creation of objects of the abstract class. Use of abstract classes is one of the most effective ways of minimizing the impact of changes in a C++ program and for minimizing compilation time. Example. TC++PL 2.5.4, 12.4.2, D&E 13.2.”
Classes in OOP: Class (computer programming), Abstract base class (ABC), Abstract class, Class body - Method body, Class browser, Class constructor (Canonical constructor, Compact canonical constructor, Normal canonical constructor, Constructor body, Default constructor, Explicit constructor invocation, Constructor modifier, Constructor overloading, Constructor signature - Method signature, Generic constructor, Constructor throw, Type of a constructor), Class declaration, Class definition, Enum class (Enum constant, Enum body declaration, Enum member), Class field (Field modifier, Static field, Transient field, Volatile field, Field initialization), Formal parameter, Class hiding (Method hiding by class methods), Class hierarchy, Class inheritance (Inheriting methods with Override-Equivalent signatures), Class initializer (Static initializer), Inner class, Class instance - Class instantiation (Class instance initializer - Preventing instantiation of a class), Class library, Class modifier, Final Class - Final method, Generic class (Generic Method - Type parameter), Class implementation file, Class invariant, Class member (Member class and interface declarations), Class methods (Method declaration, Method modifier, Native method, Method result, Method signature, synchronized method, Method throw), Nested class, Overloading (Class Overloading - Method Overloading, Constructor overloading), Overriding (Class overriding - Method overriding - Method overriding by instance methods - Method overriding by class methods, Requirements in overriding and hiding), Record class (Record components, Record constructor, Record constructor declaration, Record body declaration, Record member), Sealed class - Non-sealed class, Static method, strictfp class - strictfp method, Superclass and Subclass (Direct Subclass), Superinterface, C++ classes, C# classes, Java classes, JavaScript classes, Kotlin classes, Python classes, Ruby classes, Scala classes, TypeScript classes, Class topics.
