Java 8 vs Immutables: What are the differences?

Developers describe Java 8 as "A development environment for building applications *". It is a revolutionary release of the world’s no 1 development platform. It includes a huge upgrade to the Java programming model and a coordinated evolution of the JVM, Java language, and libraries. Java 8 includes features for productivity, ease of use, improved polyglot programming, security and improved performance. On the other hand, *Immutables** is detailed as "Java annotation processors to generate simple, safe and consistent value objects". Generate state of the art immutable objects and builders. Type-safe, null-safe, and thread-safe, with no boilerplate. Generate builders for immutable objects and even plain static factory methods.

Java 8 and Immutables can be primarily classified as "Java" tools.
