Course overview
This is the training for those who want to learn the object-oriented programming language Java from scratch.
The course covers both basic syntax and knowledge from Java’s most important libraries with support for computer science classes in the Collections Framework and the news from Java 10, communication with databases and the creation of professional GUIs. You’ll also learn how to write and run unit tests using the JUnit framework.
Exercises
- Use of functionality taken from the Java standard library
- Implementing object-oriented models in program code
- Writing program code for handling different exception situations
- Writing and running tests with JUnit
- Writing stream management programs for console and file systems
- Connecting a Java application to a database
- Building graphical user interfaces with the AWT and Swing class libraries
- Packaging of application for running on arbitrary platform
