Objectives

What are we here to do today?

Review Collections (API design; idioms and ideas for usage)

Look at Collections en masse

Examine a custom implementation

Learn to use Collections functionally (and why)

Summary

Collections are powerful

use the right interface to describe your needs; try to "design generically"

use the right implementation (or build your own!) to provide the necessary speed/size/concurrency tradeoff

use algorithms to manipulate Collections

But to truly use Collections powerfully...

... you must learn to program functionally
