Implements or extends from nested classes or interfaces.

The protected modifier cannot be used for classes at package scope, but it can be used for nested classes.
受保护的修饰符不能对包范围的类使用，但可以对嵌套的类使用。
If a class has one or more private constructors and no public constructors, other classes (except nested classes) cannot create instances of this class.
如果类具有一个或多个私有构造函数而没有公共构造函数，则其他类(除嵌套类外)无法创建该类的实例。
Also note that class definitions must appear at the top level of a module, meaning they cannot be nested classes (classes defined inside other classes or functions).
另外要注意，类定义必须出现在模块的最顶层，这意味着它们不能是嵌套的类(在其它类或函数中定义的类)。
The JMS provider must support nested map messages to convert collection classes.
JMS提供者必须支持嵌入的映射消息来对集合类进行转换。
You can traverse a nested hierarchy of classes as deeply as you'd like using this syntax.
还可以使用此语法随心所欲地遍历这些类的嵌套结构。
For example, consider a UML model that has a dependency between 2 classes (Class1 and Class2), each nested under a different package (say Package1 and Package2).
举例来说，考虑一个具有两个类(Class1和Class2)之间依赖的uml模型，每一个都嵌套在一个不同的包中(Package1and Package2)。
Also like classes, traits can contain nested trait and class definitions and classes can contain nested trait definitions.
而且，traits能包含嵌套的trait和类定义，类也能包含嵌套的trait定义。
Another issue with this solution is that its crosscutting functionality won't apply unless the classes explicitly "participate" in the collaboration, by embedding a nested subaspect.
这种解决方案的另一个问题是它的横切功能不能使用，除非类通过嵌入嵌套的子方面显式“参与”协作。
On top of the data itself, you could have nested HTML tags, each with IDs, classes, and other attributes.
