The Amber project (https://openjdk.java.net/projects/amber) is focused on small Java syntax enhancements that would make it more expressive, concise, and simpler. These improvements are going to increase the Java programmers' productivity and make their code-writing more enjoyable.
Two Java features created by the Amber project have been delivered already and we talked about them:
- The type holder var (see Chapter 1, Getting Started with Java 12) has been available to use since Java 10.
- The local-variable syntax for lambda parameters (see Chapter 13, Functional Programming) was added to Java 11.
- The less-verbose switch statement (see Chapter 1, Getting Started with Java 12) was introduced as a preview feature with Java 12.
Other new features are going to be released with the future Java version. We will look closer only at five of them in the following subsections...
