From the previous one, I understand that I understand it now, I found that Java is really difficult, just relying on some of my own foundation, now I am a Java entry. Many things in it have not really understood. This is the direction I will work next. I hope that when I have a good class in this semester, I will understand the work of my laboratory. By the way, I will understand the J2EE's frame. In order to participate in the work as soon as possible, I have to learn JSP, and I have to know about Javabean and other technologies. . This is the intention of my semester.
