Java SE Runtime Environment 8Overview

The Java SE Runtime Environment 8 (Java Platform, Standard Edition) is a major feature release. It contains new features and enhancements in many functional areas. Java SE 8 delivers enhanced developer productivity and significant application performance increases through reduced boilerplate code, improved collections and annotations, simpler parallel programming models, and more efficient use of modern, multi-core processors.

NEW

  • Addition:
    • In the previous section, we mentioned that every JavaScript object when exposed to Java APIs implements the java.util.Map interface. This is true even for JavaScript arrays. However, this behavior is often not desired or expected when the Java code expects JSON-parsed objects. Java libraries that manipulate JSON-parsed objects usually expect arrays to expose the java.util.List interface instead. If you need to expose your JavaScript objects so that arrays are exposed as lists and not maps, you can use the Java.asJSONCompatible(obj) function, where obj is the root of your JSON object tree.
  • Correction:
    • The caution mentioned at the end of Mapping Data Types section, is no longer applicable.
    • Nashorn ensures that internal JavaScript strings are converted to java.lang.String when exposed externally.
  • Correction:
    • The statement in the section Mapping Data Types, that mentions "For example, arrays must be explicitly converted,........." is not correct.
    • Arrays are automatically converted to Java array types, such as java.util.List, java.util.Collection, java.util.Queue and java.util.Deque and so on.
