Learning Method of Java

With the rapid development of the global economy, the strength of science and technology plays an important role in the development of a country. Java programming language occupies an irreplaceable position in computer programming. JAVA is mainly divided into three parts according to the application: J2se, J2me, J2ee. Let's take a look at these three sections.


1. J2se learning

When learning the Java programming language, we'll start with J2se. Because of the three sections J2se is relatively simple compared to the other two. Easy to let beginners understand the Java programming language learning and the Java language overview. And can lay a solid foundation for our future study. Do not use an IDE when you first learn J2se. And then gradually we can use it when we get familiar with it. After all, IDE technology is convenient for us to use. We can buy two books on J2se learning. The duration of J2se learning should be determined according to the learner's own level.

2. J2me learning

It is well-known that the Java programming language has the feature of embedding regions. This feature is attributed to J2me. J2me is mainly used in the development of embedded system. In the study of J2me, we should master J2se skillfully. At the same time, we also have to build the corresponding frame structure. Recall and summarize each branch in terms of the framework structure. You'll also need tools to learn the Java programming language. For those that are important, we should study again and again. You need to have a good command of drivers and applications. With the cooperation of these two programs, we can meet the requirements of embedded development. At the same time we can not relax the IDE technology learning. IDE technology is also very helpful for future learning.


When learning Java and J2ee, people come across a variety of IDEs. You can't be confused by them. Learning J2ee is about learning its own thing. Don't worry too much about IDE add-ons. When people have experience with J2se and IDE, they can start learning about J2ee. There is no doubt that Tomcat is the first choice for learning Web services. JBoss, WebLogic, and WebSphere are the three main application servers. And many companies are starting to do Websphere or WebLogic porting to JBoss application servers to achieve cost savings. Generally, Tomcat and JBoss are the first choice for everyone. These two are also relatively easy to learn. At the same time, we should also do a preliminary understanding of the development of related network programs. So that you learn the practice after the link.

After we understand these three sections, we have understood the method of learning Java. At the same time, we should also pay attention to basic learning. From understanding to proficiency to mastery of the process is inseparable from everyone's efforts. After you have finished learning the Java programming language, you should also connect the relevant knowledge of the Java language to establish a knowledge framework. In this way, we can really master the Java programming language.
