Question

Classes used only for deriving other classes are called

Answer 1

A derived class is a class created or derived from another existing class. The existing class from which the derived class is created through the process of inheritance is known as a base class or superclass.

Answer 2

Answer:

The correct answer is : Inheritance class or parent class.

Explanation:

• The process of deriving one object or class from another object or class while maintaining a similar implementation is known as inheritance in object-oriented programming.
• Another definition includes creating new classes (sub classes) by deriving them from more established ones, such as base or super classes, and then organising them into a hierarchy of classes.
• With the exception of constructors, destructors, overloaded operators, and friend functions of the base class, an object formed by inheritance inherits all the characteristics and behaviours of the "parent object" in the majority of class-based object-oriented programming languages.
• Programmers can reuse code, specify a new implementation while preserving the same behaviours, create classes that are built upon existing classes, and independently extend original software via public classes and interfaces thanks to inheritance.
• Classes in Java can be derived from other classes, just like in other object-oriented programming languages.
• A subclass is a derived class, or a class that derives from another class.
• The superclass is the class from which it is derived. In fact, every class in Java must be derived from another class.
• Thus, the question "Where does it all begin?" arises.
• The Object class found in Java.lang is the top-level class from which all other classes are derived.
• A hierarchy of classes starts with an object.
