Perhaps I am too stupid, there are

tools. At present, Java development tools are more popular with jbuilder,idea,eclipse,html development tools have Dreamweaver and so on.Six, familiar with a framework: familiar with a framework is actually becoming a Java programmer an optional knowledge, but currently development of B/s structure of the application of the development team, will almost adopt a framework to build their own application syste

stored in the object.Also, in Java, all objects are inherited from the object class. The benefit is to ensure that all objects have some common functionality that simplifies object creation and garbage collection. When a Java object is created, it is created by new to allocate space and is created in the heap. When an object is unreachable, it is automatically reclaimed by the GC. Here we can see that the

It is necessary to summarize the new knowledge of daily learning.Before I learned every knowledge, I did not how to summarize their own problems, nor how to think about how to learn better, to grasp the knowledge more firmly. From now on, I will summarize my deficiencies or feel good in every half-month, or every one months. Make yourself better. I am now learning Java Web;When you first touch the
