Java 8 is Now Released!
In a nutshell:
- Lambda expressions: a new language feature that enables you to treat functionality as a method argument, or code as data.
- Other significant enhancements and changes to the Java language and standard libraries including default methods, the new java.util.stream package, and the Date-Time API.
- Compact Profiles contain predefined subsets of the Java SE platform and enable applications that do not require the entire Platform to be deployed and run on small devices.
- Security enhancements include updates to the Java Cryptography Architecture; limited doPrivileged, a mechanism that enables code to assert a subset of its privileges; SSL/TLS Server Name Indication (SNI) Extension; and keystore enhancements.
- JavaFX documentation has been updated for this release.
- Java Mission Control 5.3 is included in JDK 8.
- Decommission of the JVM Permanent Generation space and replaced by theMetaspace.
I will publish more articles in the upcoming weeks, including tutorials on Java Mission Control 5.3 which is now part of the JDK 8.
In the meantime, I suggest that you revisit my original article on the replacement of the HotSpot PermGen space by the Metaspace. I will publish the part 2 in the upcoming weeks.
