Session abstract

Java is moving faster and faster, and a lot of features are not as well known as they should be. This tutorial reviews the ones you’re likely to have missed in old versions.

Then I will kickstart you on 9, 10 and 11 features that you never had time to look at.

My Notes

I was unsure about what to choose during this hour and finally chose this one. I hope I didn’t choose wrong…

first he speaks about the release cycle and how it has changed
@Deprecated is back wit a vengeance and had been given parameters to tell us what will happen when a version has been reached

Java 5

generics
annotations
concurrent collection
etc

Java 6

Mostly under de hood. Performance and stuff

Java 7

Brought a lot of syntactic sugar

invokeDynamic
forkJoin
Better IO
Diamond operator
binary types

multiple catches
Auto Closeable / try with recourses

Java 8

datetime api
default methods on interfaces
metaspace
completeable future
lambdas
implicitly final
method reference

Intermezzo:
Until now I have not missed anything…
If you have been using java all should be very familiar. I was hoping for stuff I missed as the title was suggesting…..

Look at the new Object part:

Method reference:

In method reference the instance is important. The method reference will capture the value and the instance can not be null. With the lambda it wil evaluate every time.
