Java中，反射是一种强大的工具。它使您能够创建灵活的代码，这些代码可以在运行时装配，无需在组件之间进行源代表链接。反射允许我们在编写与执行时，使我们的程序代码能够接入装载到JVM中的类的内部信息，而不是源代码中选定的类协作的代码。-Java, reflection is a powerful tool. It allows you to create flexible code that can be assembled at run time without representatives in the source of the link between components. Reflection allows us to write and execution, so that we can access the program code loaded into the JVM internal information in the class, instead of the selected source code in the class collaboration of the code.
