As well as providing the interfaces and adapter classes, the collections framework also includes a set of static methods for manipulating collections, including methods to search lists, suffle lists, sort lists, as well as other general functions to manipulate collections.

The Java "Collection" classes make it easy to store and manipulate collections of information. You should be familiar with the collection classes so you can leverage their many built-in features in your own code.

Outline w Java's Collection Framework — Unified architecture for representing and manipulating collections w Collection framework contains — Interfaces (ADTs): specification not implementation — Concrete implementations as classes

Java provides a set of standard collection classes that implement Collection interfaces. Some of the classes provide full implementations that can be used as-is and others are abstract class, providing skeletal implementations that are used as starting points for …

Java Collections Framework (JCF): Lists, Stacks, Queues, Priority Queues, Sets, and Maps

Includes static operations for sorting, searching, replacing elements, finding max/min element, and to copy and alter collections in various ways. (using this in lab5)

java.util.Collections, a utility class which can help to modify or operate on Java collections. This piece is based on Chapter 11 of the OCA/OCP Study Guide, a book packed with knowledge on Java programming.

What is a Collection Framework? A unified architecture for representing and manipulating collections. Includes: Interfaces: A hierarchy of ADTs. Implementations Algorithms: The methods that perform useful computations, such as searching and sorting, on objects that implement collection interfaces.

equals() and hashCode() are bound together by a joint contract that specifies if two objects are considered equal using the equals() method, then they must have identical hashcode values. To be truly safe: Objects that are equals have to return identical hashcodes.

A collection that maps keys to values A set of (key, value) pairs where keys are unique put(key, value), get(key), contains(key), remove(key) keySet(), values(), entrySet()
