什么是Nested Class
在另一个Java类中定义的Java类,Inner Class(Non-static Nested Class)、Static Nested Class、Local Class、Anonymous Class和Lambda Expression都属于Nested Class。
Static Nested Class
- 有static关键字修饰的Nested Class。
- 可以直接访问类的其他static成员。
- 不能访问对象成员。
Inner Class
- 没有static关键字修饰的Nested Class,即Non-static Nested Class。
- 所有Inner Class(包括Local Class、Anonymous Classes)可以直接访问对象成员。
Local Class
Anonymous Classes
Lambda Expression
由Java8开始支持,aims to support programming in a multicore environment by adding closures and related features to the Java language.
