N a value within a class interval, esp its midpoint or the nearest integral value, used to represent the interval for computational convenience 组值 [statistics]
First, take a use case: Suppose that you mark a class as being in progress, through your own custom InProgress annotation. No problem, right?
首先考虑这样一种情况：假设您通过定制的InProgress注释标记一个类正在开发之中，这完全没有问题，对吧？
If a class contains only static members, remember to mark the class as static or seal the class (NotInheritable) and give the class a private constructor to avoid instance creation.
如果类只包含静态成员，则要记得将该类标记为静态，或者密封该类(NotInheritable)，并且还要为该类提供一个私有构造函数，以避免实例创建。
You could mark the fields transient, but the class would still have to explicitly produce code to check whether a field was initialized every time a method accessed it.
可以将字段标记为transient，但是每当有方法访问一个字段时，类仍然必须显式地产生代码来检查它是否被初始化。
