Errata

  • The vehicles exercise is not particularly great. Craft a better one.
  • Maze.jar -- ability to see when you've exited (exception?)
  • Remove references to UAH VM.
  • Course needs overhaul to modern versions in the lectures (screenshots, instructions, and new topics):
    • TBD
  • Java added "modules" after this course was made. The course needs a lecture on modules and instructions on adding "maze.jar" and "vehicles.jar".

Modules

When you create a new JavaProject, Eclipse will use "module" features by default. We look at modules later in the course, but for now be sure the "Create module-info.java file" checkbox is NOT CHECKED.

Module 1

01 Introduction

This all needs reworking. Reference parts of the syllabus, but do so vaguely so it can be updated going forward.

There is no longer a virutal lab machine. I'll show you how to install Java and Eclipse on your own computer.

GitHub reference to the course materials. Poke around the repo for examples and hints.

02 Eclipse

A lot of this need re-doing since Java, Eclipse, and Windows have changed looks over the years. The flow and info is good.
