Java
SE 8 (March 18, 2014)
Java 8 was released on 18 March 2014, and
included some features that were planned for Java 7 but later deferred.
Work on features was organized in terms of JDK Enhancement Proposals (JEPs).
·
JSR
335, JEP 126: Language-level support for lambda expressions (officially,
lambda expressions; unofficially, closures) under
Project Lambda and default methods (virtual extension methods)]which
make multiple inheritance possible
in Java. There was an ongoing debate in the Java community on whether to add
support for lambda expressions. Sun later declared that lambda expressions
would be included in Java and asked for community input to refine the feature.]Supporting
lambda expressions also allows the performance of functional-style
operations on streams of elements, such as MapReduce-inspired transformations on collections. Default
methods allow an author of API to add new methods to an interface without
breaking the old code using it. It also provides a way to use multiple
inheritance, multiple inheritance of implementation more precisely.
·
JSR
223, JEP 174: Project Nashorn, a
JavaScript runtime which allows developers to embed JavaScript code within
applications
·
JSR
308, JEP 104: Annotation on Java Types
·
Unsigned
Integer Arithmetic[
·
JSR
337, JEP 120: Repeating annotations[
·
JSR
310, JEP 150: Date and Time API
·
JEP
178: Statically-linked JNI libraries
·
JEP
153: Launch JavaFX applications (direct launching of JavaFX
application JARs)]
·
JEP
122: Remove the permanent generation

Java
8 is not supported on Windows XPbut as of JDK 8 update 25, it
can still be installed and run under Windows XP.[192] Previous updates of JDK 8 could be run under
XP, but had to be installed after a forced installation by directly unzipping
files from the installation executable.
From October 2014, Java 8 has been the
default version to download from the official website
