It is a single class with less than 20 methods, but it turns out to have been one of the most controversial and most misunderstood APIs, having generated several "centithreads" of discussion on OpenJDK mailing lists. Indeed, Brian Goetz (Oracle's Java Language and Libraries Architect) has mentioned that one aspect of Optional was his biggest mistake in Java 8. Optional is also one of the more widely misused APIs. A brief survey of OpenJDK code revealed several embarrassing examples of Optional usage, and expert Java programmers have admitted to not making the most of this API. This session covers the history and rationale of Optional, provides recommendations and examples of proper and effective usage, shows several antipatterns and code smells and how to fix them, and finally describes some current and proposed work on Optional for Java 9. Stuart Marks is a Principal Member of Technical Staff in the Java Platform Group at Oracle. He is currently working on a variety of JDK core libraries projects, including Collections, Lambda, and Streams, as well as improving test quality and performance. As his alter ego "Dr Deprecator" he also works on the Java SE deprecation mechanism. He has previously worked on JavaFX and Java ME at Sun Microsystems. He has over twenty years of software platform product development experience in the areas of window systems, interactive graphics, and mobile and embedded systems. Stuart holds a Master's degree in Computer Science and a Bachelor's degree in Electrical Engineering from Stanford University. [VXM-7030] |
