Live-Coding zu Java 11 Migration und Local Variable Type Inference
To JAR Hell And Back - A Live Migration to Java 11
I’m sure you’ve heard about compatibility issues with upgrading to Java 9 and beyond, but did you try it yourself yet? This live coding session starts with a typical Java 8 application and runs up against and eventually overcomes the common hurdles:
- build system configuration
- dependency analysis with
- dependencies on internal APIs and Java EE modules
- split packages
To get the most out of this talk, you should have a good understanding of the module system basics - afterwards you will know how to approach your application’s migration to Java 9 and the module system.
Since Java 10 you can use
var to let the compiler infer a local
var users = new ArrayList<User>()
And that’s pretty much it, right? Surprisingly, no! There are a lot of details to consider…
- how exactly is the type inferred?
- where can I use
varand what should I look out for?
- won’t this lead to unreadable code?
After this live-coding deep dive into
var, you’ll know all about
Java 10’s flagship feature.
