Give the structure of multiple inheritance?
Java does not support multiple inheritance. It is done with the help of interfaces in java. a class can implement n number of interfaces, thus showing multiple inheritance. but a class cannot extend multiple classes in java.
Specification forms of inheritance in java?
single level inheritance eg ( class B extends Class A) Multilevel inheritance eg( class C extends class B and class B extends class A) multiple inheritance Class C inherits Class A features as well as Class B featues.This type of inheritance is not allowed in JAVA.
What is a unit inheritance?
Unit Inheritance or Single Inheritance refers to the situation where one class inherits/extends the features of another class ex: public class A extends B { ..... } The above is an example of unit inheritance.
What is single inheritance in c plus plus?
Multiple inheritance occurs when a class is derived directly from two or more base classes. class b1 {}; class b2 {}; class d: public b1, public b2 {}; // multiple inheritance class
Why does Java support multilevel inheritance?
Because it is one of the most important and widely used inheritance concepts in Java. In multi level inheritance a class directly inherits features from one class and indirectly inherits features form other classes that are in the inheritance hierarchy.

What is hierarchal inheritance?
Hierarchical inheritance is a type of inheritance in object-oriented programming where classes are organized in a hierarchical structure. It means that a derived class can inherit attributes and methods from a base or parent class, and it can further be inherited by other classes. This allows for code reuse and promotes modularity in the program.

Does structure support polymorphism?
Yes. The only difference between a struct and a class is that a struct's members and inheritance is public by default, while a class' members and inheritance are private by default. Structs can derive from classes and classes can derive from structs. As such, they are polymorphic.

Unit Inheritance or Single Inheritance refers to the situation where one class inherits/extends the features of another class ex: public class A extends B { ..... } The above is an example of unit inheritance.
What is single inheritance in c plus plus?
Multiple inheritance occurs when a class is derived directly from two or more base classes. class b1 {}; class b2 {}; class d: public b1, public b2 {}; // multiple inheritance class
What is public inheritance in java?
Inheritance is a Java feature by which we can reuse code and programming logic from one class in another class. We implement Inheritance using the extends keyword.Ex: public class Ferrari extends Car {…}Here the Ferrari Class will extend features from the Car Class.This is Inheritance. The different types of Inheritance are:Single InheritanceMulti-Level InheritanceMultiple Inheritance (Java supports only Partial Multiple Inheritance) andHybrid Inheritance
What is single inheritance in oops?
Single Inheritance is the concept of deriving a class properties from a single base class
What is the Difference between multilevel and multiple inheritance?
Multiple Inheritance : we can inherit more than one class in the same class. Multi-Level Inheritance: where one class can inherit only one base class and the derived class can become base class of some other class.
Why does Java support multilevel inheritance?
Because it is one of the most important and widely used inheritance concepts in Java. In multi level inheritance a class directly inherits features from one class and indirectly inherits features form other classes that are in the inheritance hierarchy.
Short note on inheritance?
Inheritance is used object oriented program. When you create a class, you can create a child class that inherits methods and data from the parent class.
Type of inheritances in c plus plus?
Single, multiple, multi-level, hierarchical and hybrid/virtual inheritance. Single inheritance applies when one class inherits from just one base class. Multiple inheritance applies when one class inherits from two or more base classes. Multi-level inheritance applies to a class that inherits from at least one base class that is itself derived from another base class. Hierarchical inheritance applies to a base class that is inherited by two or more separate derived classes. Hybrid inheritance combines multiple inheritance, multi-level inheritance and hierarchical inheritance. That is, where A is a common base class of derived classes B and C, and B and C are both base classes of derived class D. Hybrid inheritance is often used with virtual inheritance where B and C inherit from A virtually rather than directly. In these cases, the virtual base class is instantiated by the most-derived class in the hierarchy, D, and this instance is then shared by both B and C.
