First, the basic concept Java programs are divided into application (applications) and applets (small applications). A Java applet program must have a class that is a subclass of the applet class, and that the subclass is the main class of the Java applet. The main class must be decorated with public.

Recently, I've been thinking about a question why Formbean need to be serialized when developing with the struts framework, That is, the realization of java.io.Serializable interface, the spirit of diligent to ask me Google the next object serialization aspects of the article, although the general understanding of how to do, but still do not know why to do so; Finally, I want to solve a problem to find the root and nature of the problem, and then from the Web
