One kind of ambiguity is the Diamond Problem. Implementation of Multiple Inheritance in Java is not supported by default to avoid several ambiguity issues. Why Multiple Inheritance is Not Supported in Java? This is because the compiler is confused about whether to call the execute() from class A or class B. On executing the above code, we could find an error, i.e., an arrow mark pointing towards class C. In the Main class, we created an object of class C with the name obj itself.Class C inherits both class A, and class B.Class A, class B contains a method with the same name i.e.The below Java program has three classes A, B, C.Observe the below program for Multiple Inheritance Program in Java: Before we discuss the actual reason behind this, Let's see what happens if we try to implement Multiple Inheritance in Java. Example of Multiple Inheritance in Javaĭefinitely, there must be a reason why Java doesn't support Multiple Inheritance. Now we will be discussing an example to see what happens when we try to implement Multiple Inheritance in Java. Kindly note that Java does not support Multiple Inheritance, but we can use Interfaces to achieve the same purpose. For example, consider a newly born baby, inheriting eyes from mother, nose from father.

Many real-world examples of Multiple Inheritance also exist. This is the concept of Multiple Inheritance. In the below image, we can observe that Class C(sub-class) inherits from more than one superclass i.e., Class A, Class B. Multiple Inheritance is the process in which a subclass inherits more than one superclass. Java doesn't support Multiple Inheritance, but we can use interfaces (instead of classes) to achieve the same purpose. However, Multiple Inheritance is the process in which a class inherits properties from more than one class. Inheritance is one of the fundamental concepts of Object-Oriented Programming (OOP).īy definition, Inheritance is the process in which a class inherits all the properties (including methods, functions, variables) of another class.
