- Start reading a book for Java beginners (e.g. 2 volumes by Horstmann)
- Things that you need to know before starting next steps:
- Primitives, strings
- Loops and conditions:
if,for - Classes, fields, static fields, methods, constructors, objects (instances)
- Difference between comparing references (
==) and data (equals())
- You can read the rest of the book in parallel with this course
- Things that you can skip completely:
- AWT, Swing or JavaFX (tools for desktop apps). We're going to build a web app, desktop development is not very popular nowadays.
- Stream API (don't confuse with IO streams) and closures aren't important unless you want to understand someone else's code that utilizes them.
- Get acquainted with official Java naming/formatting conventions, there will be examples in this course so you should be able to get the drift without giving it much of a thought. But understand that it's common in dev community to get angry if they see common conventions violated. So start getting used to the conventions from the beginning.
