Getting scholars learn Java engineers "Guide Road"

1. Consider

　　1) Java if you have love for learning?
　　2) you can stop and perseverance to learn?

　　This is a simple but certainly should not ignore the problem, you are convinced that your own sense of love for Java, and there eat bitter ready, then you just might learn Java! assumed to have these two conditions, please continue to read on ......

　　2. prepare it

　　please do not put your road to learning Java and other computer technology to treat separated, contact technologies often is intricate, you should have some basic knowledge of learning Java touched, about the "CLASSPATH to how to set ah", "Download JDK knees and begged," and so on, you should not ask because the answer on the Internet too much , and even another point of view, you are not yet suitable directly learn programming?

　　1) Buy a book to learn Java.

　　JDK 6 has just launched the official version, being the market you can not buy books of JDK 6, you buy appropriate referral entry, other than the new version of Java JDK books.

　　Learning Java resources on the network a lot, but not enough foundation system with a Java entry books, is the basis for your system to learn Java.

　　2) prepare Java learning environment.

　　Prepare your learning environment is very simple, equipment JDK 6, then a similar UltraEdit, EditPlus text editor with your learning environment ( wsmdianzishangwu ), there are many articles on how to feature on the Internet. Java beginner, not recommended to use IDE thing, after knocking the code line by line, you will encounter many problems, just so that you may learn how to tune solve problems, and to deepen their understanding of Java.

　　3. Java Road based learning,

　　Java learning process, although some hard, but there is always wonderful! Mentality learning process must adhere to concentrate on, on the Internet "PK" between the words everywhere, do not be impetuous influence! Look for Java, you insist ! defeat the demons, after all, it will give you the reward of perseverance.

　　The system is divided into Java Java SE, Java EE and Java ME (JDK 5.0 early years were called J2SE, J2EE and J2ME), Java Java SE is a stepping stone, and that is also what you want to study entry, whether you choose the future which system category as the development direction, you have to start from the Java SE.

　　Learning Java SE, Java lay a good foundation; assuming that want to learn Java EE, about AWT, Swing also have a certain degree of understanding.

　　4. Java EE road learning

　　to learn Java SE, also just completed the first step in the "Long March" of.

　　Next, choose to learn Java EE or Java ME; measure selected aspects of Java EE learners will be more.

　　Learn Java EE, in a development environment is not recommended to reuse text editor, NetBeans 5.5 (the highest official version now do) very suitable for beginners.

　　4.1 learning JSP / Servlet

　　in Java EE, we must first learn JSP / Servlet (combination of Tomcat, MySQL) technology, the proposed knowledge JSP1.2 / 2.X to be the master, after all, now many are still using systems based on JSP1 .2, learn JSP, must also have some epitaxial techniques, such as: Do you have to master the basics of HTML, the best re-mastered some JavaScript (AJAX technology is now one of normalizing), CSS technology, and knowledge of XML is indispensable Less. Learning JSP / Servlet process, should be combined with learning JDBC, database development technology, after all, the vast majority of database and Java Web projects are closely integrated.

　　4.2 database development technology learning

　　Database technology is a must-do transaction systems technology, Java Web developer minimally should master the use of SQL statements! Database technology can be divided into DBA and database development technology, commonly used database have DB2, Oracle, SQL Server, MySQL, etc., you can combine the actual needs, select a database, and make great efforts to master the development of technology.

　　Remember, learning to develop database technology and learn Java EE, is relatively independent, you can learn JSP / Servlet together, learning database development technologies (such as SQL statements, etc.), perhaps first learn database development technology, after re-learning in JSP / Servlet.

　　Other developers to learn Java EE 4.3 technologies

　　Later on, be able to learn some knowledge of EJB, and now is not the latest version of EJB 3.0, and its previous version 2.X do not compare ( wsqjtysj ), it is quite different, taking into account the current EJB 2 .X there is a great use of the mall, the proposed combination of learning EJB 2.X / 3.0. In EJB learning process, together should master the use of an enterprise-class application server (such as WebSphere, Weblogic, Sun Applcation Server or JBOSS, etc., and now Sun Applcation Server 9.X and JBOSS can support EJB 3.0).

　　5. extended learning

　　so you hours of some of the Java EE perception, you will naturally want to continue to expand your knowledge, you can learn about this time Spring, Hibernate, as well as a variety of Web structures (such as Struts, JSF, Webwork or Tapestry Wait).

　　Followed by technology, continuous accumulation of experience, you will be increasing emphasis on knowledge of a higher level of analysis and planning, about this time, you can learn more knowledge related to UML, and other methods.

　　From start to finish, the process of practical learning Java technology an extremely important part. Out of practice, learning is not good technology! Maybe Java entry is not difficult, but to learn Java real, perhaps a lifetime of work.
