Maps/OOP
From charlesreid1
Notes
This page describes the application of object oriented principles to the Maps / Dictionaries data type.
- Start by describing the inheritance diagram
- Then describe the use of OOP principles - comparators, iterables, and encapsulation
- Composition design pattern for utility classes
- How to use binary search to find keys in an ArrayList containing composite objects
Inheritance Diagram
The top-level base class is the Map interface class, which defines public behaviors that Map objects must expose.
The next level down is the Abstract Map class, which defines a few private behaviors and some utility classes.
The SortedArrayMap and UnsortedArrayMap share quite a bit of code and should probably inherit from an ArrayMap base class, but they do not. They fulfill all the requirements of the Maps/ADT Maps abstract data type.
