A Java Web dynamic server is written mainly through internal classes. Dynamic classes use external classes and
Classforname is instantiated. The dynamic class constructor cannot contain parameters, and the results are all displayed. share the results with the required
Friend. There are not enough judgments,
I am grateful for pointing out the shortcomings. The following code is used:
