Interactive Java workbook
Companion book to the Interactive Java workbook task collection
Start programming in Java from scratch - beginner friendly style.
- Learn coding in the IDEA IntelliJ professional IDE for Java
- 30 theory lessons (PDF, EPUB) with 150+ executable code examples (ZIP file - course for Intellij Academy plugin)
- 480+ diverse programming tasks: answer questions, complete code, correct syntax errors, correct code, write alternative solutions (ZIP file - course for Intellij Academy plugin)
- Tasks start very easy and gradually work toward medium ones, and finally the hard ones.
- We got you covered! All tasks come with automated tests to see if your solution is correct, but also a predefined solution which can be compared side-by-side with your solution. More complex tasks come with hints to help you solve them.
- If that is not enough, and you still feel confused about some task, there are 200+ explanation videos which explain the solution to medium and hard tasks step-by-step (explanation videos are sold separately).
About
About the Book
This workbook covers the basics of object-oriented programming in the Java programming language. The
assumption is that the user knows nothing about programming and starts "from scratch."
It consists of a free companion book (in PDF or EPUB formats) but, more importantly, a multi-volume collection of tasks which are provided as ZIP files (extras) containing complete courses for the IntelliJ Academy plugin.
Programming is one of those skills that is best learned through practice. That’s why you often hear and read:
"Programming is learned through programming."
No one has learned to program simply by reading books or watching tutorials. Theory is essential, but it’s necessary to "roll up your sleeves" and program what you're learning. This means: creating your own program, doing a large number of examples, trying different solution variants, analyzing and improving other people's programs, etc.
This is exactly the motivation behind writing this workbook. There are numerous online courses, textbooks, tutorials, and educational software that contain important lessons about programming. However, there are very few interactive task collections that allow you to solidify that knowledge through concrete programming examples and diverse tasks.
Unfortunately, most of the available task collections are part of online courses, meaning that you cannot practice programming in a real-world software development environment, but through a web-browser and online-based environments with very limited features. That's why this workbook is provided as an addition of the IDEA IntelliJ enterprise-grade software development environment (actually, its Academy plugin), so one can get used to working in such a setting where all the features and tools available to a professional programmer are present.

About the Author
Hi!
I am a teacher of programming and programming enthusiast.
My passions include creating applications and teaching others how to do it.
At some point, I realized that learners abandon programming courses because:
1. they (learners) do not get enough practice
2. everything gets too hard too fast
3. getting good quality feedback during practice is difficult
What was missing was some good, pedagogically sound interactive practice materials for learning how to program. The assignments should start very easy and work gradually towards harder ones. Learning should be available (and affordable) to all, and I hope that the materials available here prove to be useful.
I am also an avid cyclist and believe in green transport solutions.
Happy coding! (and cycling also :)
