In the video, Brian Goetz and Nicolai Parlog discuss the Java language, its features, and its history. They answer questions about the language and its design decisions, and discuss how it compares to other languages. They conclude by thanking the audience and promising to return next year.

  • 00:00:00 The first session of day two of the 2021 ETE conference will be an AMA (Ask Me Anything) with Java Language architect Brian Goetz. They will discuss what records are, why they remove boilerplate, and how to design for future problems. There are multiple solutions to this problem, but one that is unpopular is picked as the winner.
  • 00:05:00 The Java language has tuples as its version of record, which are better than tuples because they are nominal and have a name for the aggregate. Records are transparent, which means that frameworks can automatically generate code for serialization or marshaling. One of the design principles adopted was that records are transparent, which means that frameworks can automatically generate code for serialization or marshaling.
  • 00:10:00 The Java language has a record type which is a formalization of the serialization proxy pattern. Records improve safety and make it easier to build safer serialization for classes that aren't records. Records are named for a game where they were not picked as the final name.
  • 00:15:00 Brian Goetz and Nicolai Parlog discuss the history of the Java language and why they believe record is a fitting name for a tuple that has a background in a theoretical background. They go on to say that record is likely not the original name for structs, and that reactive programming is a transitional technology that is likely to be replaced by other solutions in the future.
  • 00:20:00 Java 8's "event driven model" allows for more asynchronous operations, but comes at a cost of relinquishing control flow statements, simple loops, and sequential debugging abilities. In the talk, Brian Goetz and Nicolai Parlog discuss how Loom addresses these issues while still providing the benefits of reactive programming. The talk concludes by suggesting that Loom has a niche that remains largely unchallenged, likely due to the maturity of reactive frameworks.
  • 00:25:00 Brian Goetz and Nicolai Parlog discuss the Java language, its strengths and weaknesses, and how Loom compares to Core Routine. They also mention a feature of Loom that others have adopted, async await, and how it has impacted the ecosystem. They say that while the easy cases are easy, the impact on the ecosystem is not positive.
  • 00:30:00 Brian Goetz and Nicolai Parlog discuss the dangers and benefits of async await in a discussion of the Java language. They emphasize the importance of understanding how a feature will be used before implementing it, and discuss the design principles behind Java features. They also mention local variable type inference as an example of a feature that is both easy to use and well-designed.
  • 00:35:00 Brian Goetz and Nicolai Parlog discuss the benefits and drawbacks of Java's new feature, var. They state that while some code may become worse, other code may become much better because things will re-equilibrate at a simpler place. They also mention that the project to make the grawl compiler the jet compiler used by Hotspot is ongoing.
  • 00:40:00 Java has been working on adding pattern matching and destructuring to its language for a long time, and it looks like this will be in the next release. The feature will make it easier to work with data, and will also allow for more ad hoc polymorphism over different types of data.
  • 00:45:00 The Java language is getting closer to the boundary where untyped data comes in from the messy outside world. There are many potential uses for pattern matching in Java, including instance of and type pattern matching. However, this feature can also lead to more bifurcating of code, as developers are forced to use the new way of doing things or give up.
  • 00:50:00 Java developers are encouraged to use streams and pattern matching over for loops, as these techniques provide a greater benefit than the complexity incurred. The trend of promoting new techniques in a way that doesn't impact the older codebase is called a "noisy ecosystem," and it is hoped that after a few iterations, good advice will emerge.
  • 00:55:00 Brian Goetz and Nicolai Parlog answer questions about the Java language. Brian mentions that he likes Haskell for its strictness and Clojure for its different programming model. They conclude by thanking the audience for attending and promising to return next year in person.
