#17: Custom Localized Date-Time Formats

You can have a `DateTimeFormatter` with a custom pattern: `ofPattern("y-MM-dd")`

You can have a localized one, too:
`ofLocalizedDate(FormatStyle.SHORT)`

And since #Java19, custom localized one works, too: `ofLocalizedPattern("yMM")`

#5: `newHashSet`

The `HashSet` constructor that takes an `int` argument interprets that as capacity, not as the number of expected elements. Once the number of elements reaches $LOAD-FACTOR (by default 75%) of capacity, the set resizes itself.

To avoid that resize with the constructor you either need to compute capacity from number of expected elements or set the load factor accordingly.

Or, since #Java19, call `HashSet::newHashSet` and pass the number of expected elements.

Lots of learning to be had at the return of the #Belgian Java User Group where the great @ammbra1508 talked about new features in #Java 19 . Kudos to @TCoolsIT for reviving (resuscitating?) the group 👏 And nice to see @geoffreydesmet there as well 🙂

After a short intro, our star speaker of the evening is kicking it all off! @ammbra1508 talking about #java19.

Java finally has virtual threads #java19

Just a single day to go until J-Fall! For the 6th consecutive time I'll be speaking at the largest #Java event in my home country. 🇳🇱 At 8AM in Room 5 @peterwessels, me & a room full of early birds will dive into #PatternMatching! #Java19 #JFall

What's new in Java 19 for us, developers ?

Of course there's already a #Java19 related issue for @OpenLibertyIO@twitter.com. I wish I could be the first to think of such things 🤣

Thanks @Thi_Hup@twitter.com! 👋🏻
