Object Class

Object Class

Every class in Java is supposed to extend the Object class by default. In case a user class extends some other class (e.g., if myclassextends yourclass), then is it not multiple inheritance?

Multiple inheritance is when one class inherits the behavior of two or more parent classes. Inheritance of the type you’ve described iscalled single inheritance because “myclass” inherits Object through “yourclass” rather than apart from it.

Multiple inheritance can be achieved in Java through interfaces, but inheritance of implementation requires the use of aggregation and delegation as described in theanswer to the question with the subject “Multiple Inheritance.”
