Unit 2

Thus far, most examples and programs have consisted of writing code in a single file, often just inside one method. These small programs are ideal for learning new constructs and concepts.

In contrast, modules 2, 3 and 4 are intended to show how larger programs are constructed out of many methods and classes, often in multiple files. As a result, there are many "moving parts", and this can seem a bit overwhelming at first.

In each module, we will walk you through building an application in steps, with some code already provided, with the following goals:

• See how an application comes together.
• Improve code reading skills.
• Put your programming skills into practice by working with a more substantial application.

Keep in mind:

• None of the material in these modules will be on the exam.
• We will take the two highest module scores from modules 2, 3, and 4, provided that a good faith effort is made in trying out all three.
