  • Improves the type interference for generic instances
  • Library support for Elliptic Curve Cryptography (ECC) algorithms
  • Update the Rowset 1.1 and the JDBC 4.1
  • Automatic resource management in try statements
  • Concurrency and Collection Updates
  • 64-bit compressed pointers
  • JVM support for the dynamic types languages

Java 8 and its features

The Java SE 8 is a comprehensive version of the development platform that brings important changes and upgrades to the Java programming language. It includes an improvement in the JavaScript engine, new APIs for the Date and the Time manipulation and faster JVM, etc. Java SE 8 is a giant leap for the programming language.
