Work through Udacity videos Lesson 9 up to "Implementing Comparable".
Read Sections 10.1.1, 10.1.2, 10.2., 10.3 of the textbook. Note that the Udacity videos talk about interfaces first, so you skip to chapter 10 of the textbook.
Take the quizzes on Monday and Thursday.
Turn in the draft of Homework 14 on Wednesday and the final version on Sunday.
Work through Lab 13 and join a Webex session if you have a question and when you are ready show off your work.
Week 13 homework solutions are here.

{
Measurable[] result = new Measurable[items.size()];
for (int i = 0; i < items.size(); i++) { result[i] = items.get(i); }
return result;
