Inheritance

Inheritance

1. Extending a class or subclassing or inheriting a class

   • Inheritance allows you to add methods that don't exist in the original class while still retaining the original features.
     • Java does not inherit from multiple classes. Can't extend a class from two different classes.
       • Interface gets around this issue and supports the functionality of multiple inheritance.
     • Can continue to subclass as needed. The final keyword prevents further subclassing.
       • Multilevel inheritance has limits to access to distant classes. Grandparent ---> Parent ----> Child Child has no access to grandparent.
