| Prerequisites |
|
Intermediate knowledge of Java (at least one university course completed), basic knowledge
of algorithms.
|
| Course description |
|
The first part of the course reinforces knowledge of Java. It is assumed that a student is already
familiar with the Java programming language, at least on intermediate level, so that material can be presented in the form of
a discussion. Topics such as the outcomes of executions of different Java programs, possible errors,
misinterpretations and pitfalls of the language will all be addressed. This course prepares students for international
examinations of Java expertise.
The second part of the lecture demonstrates the use of Java in various scientific areas. Topics are
taught in the form of step by step solutions to specific problems. Then the user is introduced to numerous possibilities of applying Java
and is shown where to find further information. At the end of each class
examples of issues are presented as an inspiration for the students to develop their own applications.
