Textbook

We will be using the Textbook Objects First with Java - A Practical Introduction using BlueJ, Pearson Education, 2016, 6th edition by David Barnes and Michael Kölling. See the publishers Pearson Book Page.

There is a German translation available: Barnes, David J., Kölling, Michael: Java lernen mit BlueJ. Pearson, 2017, 6. Auflage. Pearson Book Page.

There are copies available in the library, and you can also obtain an older edition - examples and chapter order vary, but the general content is mostly the same apart from the newer chapters on lambdas and streams. More material and info on the chapter order can be found on the book’s web page: https://www.bluej.org/objects-first/

The autors have recorded videos for most lectures: Complete Video Playlist, Older Video Notes (with previous edition chapter numbers)

Java Tutorials

There are many Java Tutorials out there on the web on the topics we cover. Many will prove useful, however, do use them as practice to gauge the quality and applicability of your findings before relying on them.

A comprehensive resource for the Java language are the Tutorials by Sun/now Oracle; especially the Trail “Learning the Java Language”.
