Java Self-paced roadmap

First of all to learn javase, at the same time, and javase learning synchronization, it is recommended to study the data structure and algorithm .

After this, you can choose to J2ME, or Java GUI, socket programming, such as the direction of efforts, but through the first method, you can easily filter out this direction, temporarily toward the direction of the EE.

After the javase is complete, you can try to complete some small projects and focus on the design pattern , without forcing yourself to be able to master all the details.

Master a programming tool, such as Eclipse.

Database, you can choose to start with either Oracle or MySQL.

JDBC, connect the database with Java.

You can choose to cut into hibernate in this place, or you can choose to post struts.

HTML CSS JavaScript, these things are necessary to do Web project content.

Servlet JSP, server-side required.

XML AJAX, new trends cannot be understood.

Make some small projects. such as BBS, message system, student status management, mall, and so on, some business logic is relatively simple to do.

Typical applications of STRUTS,MVC

A model of hibernate,or mapping.

Spring IOC + AOP, Object-oriented + facets-oriented, complete journey.

Add the elements of struts, Spring, and hibernate to your previous small project.

To study the business logic of a variety of business projects, you can add a strong pen to your resume.

The return of Ejb3.0,java after many detours is worth studying.

SOA, the industry's ironclad future trend, to follow closely.
