| There will be some programming assignments each week, possibly followed by a final exam...
|
|
| code
|
The programming examples are collected in directories that more or less correspond to the chapters of the lecture notes.
|
| ftp
| Archived copies of the programming examples, the documentation, and the overheads as well as development kits, browsers, and related tools are available only from within the university of Osnabrück's local network using the file transfer protocol.
|
|
|
| A good starting point to look for Java tools on the Web are the Java Solutions and the Java Products & APIs at Sun Microsystems as well as Jeff Poskanzer's Home-Page.
|
|
| html
| Here are the overheads used in class and the Java documentation and the examples from Sun's JDK (1.2.1).
|
|
| pdf
|
PStill was used to convert and index the overheads from the html area using the Portable Document Format. This is primarily suitable for printouts and (under Windows) for text searches.
|
|
|
| Depending on the computing platform you need special viewers or plugins which have to be installed beforehand.Viewers for Windows and Linux are available in the ftp area.
