#Java14

#Java14 is introducing multiple language changes. Check out this blog post to know how you can use all the new #Java14 language features in #IntelliJIDEA 2020.1: To unleash their potential, use these features in combination with other features.

Records are intended to be simple data carriers, a version of tuples that fits into Java’s established type system in a logical and consistent manner. #java14 #openjdk #java @kittylyst

Wooohooo for Java Records! Played around with this #Java14 preview feature yesterday and look how much less code is needed! 🔗

Do you want to work with #Java14, but don't know why or how? Check out the screencast on how to use #Java14 language features with #IntelliJIDEA 2020.1, using a ton of examples:

Java 14 new feature, record, or data class, love it. #Java #Java14

Sometimes (e.g. during TDD) we define what our classes look like by using them, and then have IntelliJ IDEA generate the correct code. IntelliJ IDEA 2020.1 lets us generate a #Java14 Record, either in its own file or as an inner class #TheDriveToDevelop

Did you know? Accessor methods for #Java14's Record classes don't start with the word "get"! IntelliJ IDEA 2020.1 does the right thing when generating "getters" for record classes, in case you want to add any logic to the accessors. #TheDriveToDevelop

#Java14 pattern matching brings name shadowing to the next level of craziness. Here I add or remove the `final` modifier for the `FLAG` field, which is accessed only in unreachable `if` branch. This actually changes the program semantics! #ProgrammingIsFun.

Not yet running on #Java14? Do you even code, bro?

“These features remove boilerplate code and make code highly expressive, and intuitive—easy to both write and maintain.” @java Champions explain why #Java14 makes code super expressive. (via @Forbes)

IntelliJ IDEA 2020.1 (currently EAP) not only supports the new #Java14 Record syntax, but can generate new record classes for you to help you get started. Try it now! (download #Java 14: #TheDriveToDevelop

April's #Java Annotated Monthly is out now! Containing news on #Java14, IntelliJ IDEA 2020.1, and a whole new section on tips for remote work.

#PatternMatching in #Java14 extends the instanceof operator with a type test pattern. Download #IntelliJIDEA 2020.1 EAP and check it out today: Stay tuned for more updates on using Java 14 with IntelliJ IDEA. #TheDriveToDevelop

As we celebrate 25 years of #Java this year, today's announcement of #Java14 has piqued the community's interest! Please join the March 26th webinar to learn about some of the new features from @aureliog. Registration: #OpenJDK #JDK #JDK14

IntelliJ IDEA 2020.1 can generate compact constructors for our #Java14 Record classes, so we can easily add validation (for example) for our record components. Try out #Java 14 preview features in IntelliJ IDEA now! #TheDriveToDevelop

#Java14 improves error messaging for NullPointerException so it shows which variable was null. Useful when the NPE is thrown on a line with method chaining. This is disabled by default in #Java 14. To enable, add command-line option -XX:+ShowCodeDetailsInExceptionMessages

Since Records are a new Preview Feature in #Java14 we might not be familiar with the syntax. IntelliJ IDEA 2020.1 can help, for example allowing us to switch between the new compact constructor form and a canonical constructor. Try it! #TheDriveToDevelop

IntelliJ IDEA offers all the automatic refactoring we'd expect for #Java14 Record classes. For example, we can change the signature of the record header to switch the order of the parameters #TheDriveToDevelop
