Interfaces for Behavior Specification Leverage interfaces to define contracts for behavior. Implementing interfaces allows fo...
Inheritance in Java refers to the ability of child classes to inherit or acquire all the non-private properties and behaviors from the parent class. Inheritance is one of the four pillars ofobject-oriented programmingand is used to promote code reusability among the classes in a hierarchy. In t...
