Safe And Anti Static 安全防静电
You should also remember that static classes that preserve state between method calls should be made thread safe by default.
您还应该记得，在方法调用之间保留状态的静态类在默认情况下应该是线程安全的。
Since it is thread safe by design, you might cache it in a public static final variable, or wrap it in a singleton pattern after creation for later access.
因为根据设计它是线程安全的，创建它之后可以把它缓存在一个公共静态最终变量中，或者包装在单实例模式中以供以后访问。
Note that readdir is not thread-safe, because the returned structure is a static variable stored in the function library.
请注意，readdir不是线程安全的，因为所返回的结构是存储在函数库中的一个静态变量。
