Definition: Packages function like directories. They help organize classes and avoid naming conflicts.Class Uniqueness: Classes with the same name are

Inheritance allows one class (child or subclass) to use the properties and methods of its parent class (superclass). This greatly enhances code reusab

Just like primitive types, class instances can also be typecast in Java, particularly between classes that declared an inheritance relationship (exten
