1. Single Inheritance
A Scenario where one class is inheriting/extending the behavior of just one super class.
Ex: public class Ferrari extends Car {…}
2. Multilevel Inheritance
A Scenario where one class is inheriting/extending the bahavior of another class which in turn is inheriting behavior from yet another class.
Ex: public class Automobile {…}
Public class Car extends Automobile {…}
Public class Ferrari extends Car {…}
This multilevel inheritance actually has no limitations on the number of levels it can go. So as far as java goes, it is limitless. But for maintenance and ease of use sakes it is better to keep the inheritance levels to a single digit number.
3. Hybrid Inheritance
This is the scenario wherein your java code exhibits traits of more than one of the inheritance types explained above. Going with the example above again:
Public class FerrariF12011 extends Ferrari implements Car, Automobile {…}
The above is a combination of both single and multiple inheritance.

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
Specialization form of inheritance?
Inheritance refers to the concept by which the features from one class can be extended/made available in other classes. Java supports 3 forms of inheritance * Single Inheritance * Multiple Inheritance * Multilevel Inheritance (Can be implemented using interfaces)
How multiple inheritance is done in java?
Java doesn't have multiple inheritance proper. It is possible for a class to implement different interfaces - however, in this case, only the method names are "inherited", not their contents. It is also possible to use composition instead of inheritance: an object can contain objects of different classes, and use the methods of the objects it contains - but this, too, is a different mechanism than inheritance.
How ploymorphism and inheritance is different from that in Java and c plus plus?
C++ allows multiple inheritance while Java does not. In my opinion, multiple inheritance is not useful because it can get very confusing very quick. For polymorphism, C++ does early binding by default, while Java does late binding by default. Late binding is more useful than early binding.
What does java not support?
Java does not support multiple inheritance.......
What is ambiguity in multiple inheritance?
Java does not support multiple inheritance
What kind of inheritance is not allowed in java?
Java does not allow the multiple inheritance of concrete classes, though it does allow a "hybrid" inheritance of one concrete class and multiple interfaces.
What is problem in multiple inheritance?
Java does not support direct multiple Inheritance. Harder to implement, not every language support it: C++ does, Java does not.
Why object is the super class in java?
The answer to this is related to the idea of inheritance in general - the idea of inheritance is that you define a common set of behaviors, that apply to all subclasses. Anything defined in the "Object" class is available to all classes you create. Look in the documentation for the description of the "Object" class, to see what methods are available in all Java classes.
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.
How does inheritance support multiple inheritance in java in example?
Actually, java does not support multiple inheritance. You can achieve partial multiple inheritance using interfaces but java is not like C or C++ where you can do direct multiple inheritance. However, you can achieve partial multiple inheritance with the help of interfaces. Ex: public class FerrariF12011 extends Ferrari implements Car, Automobile {…} And this is under the assumption that Car and Automobile are interfaces. Here if you see, though you don't inherit concrete code from the Car or the Automobile interface, you do inherit skeleton methods that determine the way your class eventually behaves and hence this can be considered partial Multiple Inheritance.
Need of interface in java?
Interfaces are used in Java to accomplish most of the goals of Multiple Inheritance. For several reasons, Java only supports Single Inheritance for classes - i.e. a class can have only a single parent. The use of Interfaces is how Java attempts to implement most of the positives of the concept of Multiple Inheritance while avoiding its pitfalls.
