Softwarelab: Implementing Regular Expressions in Java


Winter Term 2015/2016



+49 241 80 21712




The students should master in small groups and in the frame of collectively created specifications the primary elements of software engineering. It involes the development of regular-expression-engines and their practical application. While implementing they should consider the pros and cons of the different algorithms in their respective fields of application. They should create a documentation of the source code in LaTeX.

Part I: Regular Expressions

Regular expressions are a common tool for programming. They can be used to find text snippets of a certain structure, that satisfies the so called regular expression. With the help of regular expressions spam-filters are implemented. During this practical course you will get to know two different approaches, that will also be implemented at a later time. Furthermore a parser for regular expressions should be created.

Part II: Working with LaTeX

In the fields of science journalism the professional typsetting system LaTeX is used to create papers, essays and books. While office programs use WYSIWYG, meaning the screen and print are identical, LaTeX documents need files that also include logical structures and formating. The latex binary creates .dvi files, that are device independent and can be translated into a variety of other file types. To print them, it will be necessary to create a ps or pdf file. The tasks will include, among other things, text formating, tables, formulas, graphics and presentations.


This practical course is only open to students with a major in communications-engineering either bachelor or magister.



Registration for a slot can be done here Online-Registration. Beware the deadlines.

The date for the inital appointment will be send via email.


The tasks of the practical course are usually worked on during certain dates in the machine pool of the computer science faculty. The appointments will be determined in a dialog with the participants. Certain parts of the tasks can be worked on from home. During the lecture free time in the winter semester certain basics have to be prepard before beginning the practical course.
