What is the java learning route? Ask the great god for guidance!

In the world of programming, java has always been the favorite programming language for enterprise development, and it is still quite good from the current employment situation of java. Due to the need of mobile phone Android development, many people also began to learn java. Geek camp feels that although the demand for java developers is increasing now, it does not mean that the technology of being a java developer can remain unchanged, and Java technology will be updated quickly. Moreover, in domestic training institutions, Java students are all mass-produced, so there is also competitive pressure. Therefore, after learning the basics of java, many people turned to the fiery development of Android. Geek Camp will analyze various general learning routes of java today.

To sum up, there are two directions to do java: web enterprise development (JavaWeb J2EE) and mobile phone android development. The premise of these two directions is J2SE. J2SE is not that simple. Only by learning more and more will you realize the essence of java.

1.HTML+CSS+DIV, the front end will be used. As a researcher, you should at least write some pages simply, which is the basis that many programming languages need to know.

2.JAVASCRIPT, you need this if you want to use some special effects, but you don't need to be proficient. When you need to use JS, you can use Jquery as a proxy. Jquery is very studious and has a very useful JS framework. He can easily accomplish seemingly complicated and gorgeous effects.

3.Ajax, a front-end asynchronous interaction technology, is worth studying.

JSP, Servlet and JAVAbean do not advocate embedding Java code in JSP until now, so they only regard it as the view layer and embed some tags such as JSTL and Struts2 tag library to become dynamic pages. We should focus on Servlet, including filters and listeners, which are the underlying foundation and principle of Struts2 or the future WEB framework.

5. Strut 2+Hibernate (Orjpa)+Spring, a very popular development framework at present. In fact, getting started is very easy, but the key is to understand the principle.

6.Web service technology enables different applications running on different machines to exchange data or integrate with each other without the help of additional specialized third-party software or hardware. No matter what language, platform or internal protocol is used, applications implemented according to the Web service specification can exchange data with each other.
