Some More Tools of the Trade

In this chapter you are introduced to the use of breakpoints and user initiated exceptions. Breakpoints in particular are extremely useful and you will find that you will make extensive use of them, not just for debugging but also to help you understand how objects are behaving. The use of the file in and file out facilities for saving classes onto your host file system are also discussed. These are important as without this ability you would loose any source code you developed when you started a new image. Finally the use of the changes file and projects are discussed.
