In Java, classes provide inheritance through a hierarchical structure where a subclass can inherit fields and methods from a superclass, allowing for code reuse and polymorphism. This enables the subclass to extend or override behaviors of the superclass. In contrast, Java does not support inheritance through structures (often used in languages like C), as structures in Java are not a distinct type; instead, classes are the primary way to create complex data types with inheritance capabilities. Consequently, classes are the primary mechanism for implementing inheritance in Java, while structures are not a feature of the language.
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.
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.
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.
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
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.

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.
Direct inheritance refers to a situation where a class (subclass) inherits properties and methods directly from another class (superclass) without any intermediary classes. In contrast, indirect inheritance occurs when a subclass inherits from a superclass that itself inherits from another class, creating a chain of inheritance. This allows subclasses to access attributes and methods from multiple layers of superclasses, promoting code reuse and a more organized class structure.
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.
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
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
Single Inheritance is the concept of deriving a class properties from a single base class
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.
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.
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.
