Reflection (Refection) in a programming language refers to the ability to dynamically load a class at program run time. It is related to introspection (introspection), which means that the program can get a description of a type, such as getting all the interface definitions of a class, all the parameters of an interface. When the programming language has these language features, it can solve the problem of

is equivalent to self-destruct, because some browser versions crash when processing an incorrect script (very few, but there are). If the user's JavaBean is dynamically rolled out in a complex HTML language at run time, the user will fall into a debugging nightmare. In addition, complex HTML will limit the lifetime and flexibility of JavaBean. 3. Do not provide any options.
