Hope you have got a better understanding towards the different types of inheritance in Java. As you can ClassA will be acting as the Parent class for ClassB & ClassC and ClassB & ClassC will be acting as Parent for ClassD. Flow diagram of the Hybrid inheritance will look like below. Again Hybrid inheritance is also not directly supported in Java only through interface we can achieve this. Hybrid Inheritance is the combination of both Single and Multiple Inheritance. Assigning ClassD object to ClassD referenceĭisp() method of ClassA 5. Subclasses of a class can define their own unique behaviors and yet share some. This principle can also be applied to object-oriented programming and languages like the Java language. Hierarchical Inheritance Example public class ClassA The dictionary definition of polymorphism refers to a principle in biology in which an organism or species can have many different forms or stages. ClassA will be acting as a parent class for ClassB, ClassC and ClassD. As per the below example ClassA will be inherited by ClassB, ClassC and ClassD. In Hierarchical inheritance one parent class will be inherited by many sub classes. Assigning ClassC object to ClassC referenceĭisp() method of ClassC 4. MultiLevel Inheritance Example public class ClassA In Short ClassA parent for ClassB and ClassB parent for ClassC. ClassB inherits the property of ClassA and again ClassB act as a parent for ClassC. In Multilevel Inheritance a derived class will be inheriting a parent class and as well as the derived class act as the parent class to other class. But you can achieve multiple inheritance in Java using Interfaces. (C++ Supports Multiple Inheritance). As the Child class has to manage the dependency of more than one Parent class. Multiple Inheritance is basically not supported by many Object Oriented Programming languages such as Java, Small Talk, C# etc. Multiple Inheritance is nothing but one class extending more than one class. Assigning ClassB object to ClassB referenceĭisp() method of ClassB 2. Single Inheritance Example public class ClassA Single Inheritance is the simple inheritance of all, When a class extends another class(Only one class) then we call it as Single inheritance. The below diagram represents the single inheritance in java where Class B extends only one class Class A. Here Class B will be the Sub class and Class A will be one and only Super class. Lets see about each one of them one by one.
