How do you define base class?

Base Class: A base class is a class in Object-Oriented Programming language, from which other classes are derived. The class which inherits the base class has all members of a base class as well as can also have some additional properties.

What is a base class and derived class?

A base class is an existing class from which the other classes are derived and inherit the methods and properties. A derived class is a class that is constructed from a base class or an existing class. The base class is also called superclass or parent class. The derived class is also called a subclass or child class.

What is base class in C#?

A base class, in the context of C#, is a class that is used to create, or derive, other classes. Classes derived from a base class are called child classes, subclasses or derived classes. A base class does not inherit from any other class and is considered parent of a derived class.

What are the different types of inheritance?

The different types of Inheritance are:

• Single Inheritance.
• Multiple Inheritance.
• Multi-Level Inheritance.
• Hierarchical Inheritance.
• Hybrid Inheritance.

Is final class is a base class?

Note that it is not necessary to declare final methods in the initial stage of inheritance(base class always). We can declare final method in any subclass for which we want that if any other class extends this subclass, then it must follow same implementation of the method as in the that subclass.

What is the base class of all classes?

Object class is the root or superclass of the class hierarchy, which is present in java. lang package. All predefined classes and user-defined classes are the subclasses from Object class.

What is the purpose of base class?

A base class is a class, in an object-oriented programming language, from which other classes are derived. It facilitates the creation of other classes that can reuse the code implicitly inherited from the base class (except constructors and destructors).

What is boxing in C#?

Boxing is the process of converting a value type to the type object or to any interface type implemented by this value type. The concept of boxing and unboxing underlies the C# unified view of the type system in which a value of any type can be treated as an object.

How many specifiers are used to derive classes?

3 specifiers
Explanation: There are 3 specifiers used to derive a class. They are private, protected and public. 3. Which specifier makes all the data members and functions of base class inaccessible by the derived class?

Can two classes inherit from each other?

It is not possible.

What is intermediate base class in Java?

A class which acts a base class for a derived class but it itself is derived from another base class (at a higher level of inheritance hierarchy) is called an “Intermediate Base Class”.

Which of the following is called intermediate base class inheritance?

So ‘Teacher’ is called the intermediate base class inheritance. Formal definition- A class which acts a base class for a derived class but it itself is derived from another base class (at a higher level of inheritance hierarchy) is called an intermediate Base class.

What is the difference between base class and derived class?

A base class is also called parent class or superclass. Derived Class: A class that is created from an existing class. The derived class inherits all members and member functions of a base class. The derived class can have more functionality with respect to the Base class and can easily access the Base class.

What is base class in C++?

Base Class: A base class is a class in Object-Oriented Programming language, from which other classes are derived. The class which inherits the base class has all members of a base class as well as can also have some additional properties.
