Context

The purpose of this unit is to explain how Java can be used to create stand-alone applications suitable for non-trivial, real world tasks. Most real-world applications manipulate files on the users’ computers, so this unit introduces the subject of how Java works with files. Relating to files, and in fact almost all non-trivial programs, is the concept of Java exceptions — the handling of special cases and errors.
