While the previous course was about how to describe abstractions using classes, this one focuses on using objects based on examples from real libraries. Building call chains, working with data structures, and handling dates and strings in an object-oriented style are just some of the things we'll encounter in this course.
This course won't teach any new syntax, we've seen plenty of it already. OOP is a complex subject, and it's important to introduce new concepts fairly carefully, waiting until after we've gained some experience with basic concepts. A separate topic that will run like a thread through the rest of the course is design patterns or patterns – approaches for solving typical problems.
