First Look: Java 10 and Java 11

Get a first look at the new features in Java 10 and Java 11, including local variable type inference, application class-data sharing, improved garbage collection, and more.

Java 10 and 11 have arrived and developers are eager to use the new features in their projects. This course reviews the latest and greatest versions of Java, released in March and September 2018. Instructor Kathryn Hodge starts with the most noteworthy enhancements in Java 10, such as local variable type inference with the var keyword, application class-data sharing (CDS), thread-local handshakes that enable pausing of a single thread, and Gral, the experimental just-in-time compiler. Then she moves onto Java 11, which allows var to be used for lambda parameters; standardizes the HTTP client; and enables the Java launcher to run a program supplied as a single file of Java source code. Many other performance and security enhancements are reviewed along the way. This course is a great resource for any developer who wants to get up to speed quickly with the latest developments in the Java platform.
