*  #### Java 编程语言 ####
    
    #### [Java Programming Language][] ####
    
     *  Lambda 表达式是一个新的语言特性，已经在此版本中引入。该特性让您可以将功能视为方法参数，或者将代码视为数据。使用 Lambda 表达式，您可以更简洁地表示单方法接口（称为功能接口）的实例。
     *   Lambda Expressions, a new language feature, has been introduced in this release. They enable you to treat functionality as a method argument, or code as data. Lambda expressions let you express instances of single-method interfaces (referred to as functional interfaces) more compactly. 
     *  方法引用为已经具有名称的方法提供了易于理解的 lambda 表达式。
     *   Method references provide easy-to-read lambda expressions for methods that already have a name. 
     *  默认方法允许将新功能添加到库的接口中，并确保与为这些接口的旧版本编写的代码的二进制兼容性。
     *   Default methods enable new functionality to be added to the interfaces of libraries and ensure binary compatibility with code written for older versions of those interfaces. 
     *  重复批注支持对同一个声明或类型的使用多次应用相同的批注类型。
     *   Repeating Annotations provide the ability to apply the same annotation type more than once to the same declaration or type use. 
     *  类型批注支持在使用类型的任何地方应用批注，而不仅限于声明。与可插拔类型系统结合使用时，此特性可改进代码的类型检查。
     *   Type Annotations provide the ability to apply an annotation anywhere a type is used, not just on a declaration. Used with a pluggable type system, this feature enables improved type checking of your code. 
     *  改进类型推断。
     *   Improved type inference. 
     *  方法参数反射。
     *   Method parameter reflection. 
 *  #### 集合 ####
    
    #### [Collections][] ####

     *   Classes in the new `java.util.stream` package provide a Stream API to support functional-style operations on streams of elements. The Stream API is integrated into the Collections API, which enables bulk operations on collections, such as sequential or parallel map-reduce transformations. 
     *  针对存在键冲突的 HashMap 的性能改进
     *   Performance Improvement for HashMaps with Key Collisions 
 *  **[紧凑 profile][profile]**包含 Java SE 平台的预定义子集，并且支持不需要在小型设备上部署和运行整个平台的应用。
