Since Java 10, type inference in Java has been extended to declarations of local variables with initializers, thus reducing the ceremony associated with writing code. Although seemingly simple at first sight, the feature comes with a series of restrictions making its usage rather tricky at times. In this live-coding session, we push the limits of local variable type inference and examine its behaviour through a series of 40 examples. We do this in the form of a quiz, and focus on situations where the type inference doesn’t work, or leads to unclean code. Come and test your intuition and knowledge of local variable type inference, and learn how to use it well in practice!
Scheduled on Saturday from 15:00 to 15:50 in Room 1
When Java 8 was first introduced, it revolutionized the way Java applications were written by providing the core constructs for asynchronous programming and handling data streams. With Java 9-12, these capabilities were extended to the level that allows us to write truly modern, reactive applications with the JDK. In this live-coding session, we explore the building blocks or reactive systems available in the JDK today, which create 8 levels of reactive programming. We specifically focus on JDK 9-12 features, such as updates to the Stream and CompletableFuture APIs, Reactive Streams publish-subscribe framework, HTTP/2 client, and more.
