The Java compiler provides some rules to determine which default method a particular class uses. A class can implement more than one interface. In Java 8 Default methods were introduced. Java didn’t support this type of multiple inheritance untile Java 8. Multiple inheritance of implementation: This means the ability to inherit method definitions from multiple classes. So this type of multiple inheritance is not supported in Java. Java does not permit to extend more than once class. Multiple Inheritance of State: This means ability to inherit fields from multiple classes. Let’s look at various types of multiple inheritance and which of them is supported by Java. Multiple inheritance is a feature in which an object can inherit attributes and methods of the parent object. What is multiple inheritance? Does Java support multiple inheritance? An Order object depends on Customer object. An Order Object cannot be created without the Customer object. The other may or may not depend on the first object. package ĭependency is a a form of relationship in which one object depends on another object. This behavior is referred to as virtual method invocation. An overridden method is invoked at run time, no matter what data type the reference is that was used in the source code at compile time.
