Proficient in java basics, advanced java programming, and common java design patterns
macro aspect
1. JAVA.
If you want to become a JAVA (senior) engineer, you must learn JAVA. Ordinary programmers may only need to know some JAVA syntax structures to cope with. But to become a JAVA (senior)
engineer, you need to do a more in-depth study of JAVA. You should study more about JDBC, IO package, Util package, Text package, JMS, EJB, RMI, threads. If possible, I hope you
can browse all JAVA packages and know the approximate API, so that you will find that many functions you want to achieve can be achieved through the JAVA API, so you don't have to spend too much brains. .
Second, the design mode.
It's actually easy to write code, and I'm sure you feel the same way. But how to write well is more difficult. The word "good" includes code reusability, maintainability, extensibility, etc. How to write good
code often relies on some design patterns. Of course, long-term code experience accumulation, as long as you pay attention, will make you form your own code style. I believe that your code is also more in line with code reusability, maintainability, and scalability.
But since the predecessors have summed up the experience for us, why don't we step on the shoulders of the predecessors?
3. XML.
It is almost impossible in today's systems not to use XML. XML is very powerful, it can do data conversion, system configuration, and even save your system business data. So you must understand
XML, including its syntax, structure. You also need to be proficient in using some APIs for parsing XML, such as JDOM, SAX, etc. Because in our general projects, XML often plays
the role of system configuration information, you need to use these APIs to parse the configuration information and develop a perfect project .
4. Be proficient in using one or both frameworks.
"Framework will have a lot of reusable code, good hierarchical relationship and business control logic, framework-based
development allows you to save a lot of development costs." I hope you can be proficient here, and more hope that you can understand the idea of the framework through the use of the framework. In this way, when you develop a project, your thinking will be broadened. For example, you
will think of separating SQL statements from your JAVA code. For example, you will consider configuring your business logic into XML or database, so that the whole project can be easily expanded. .
5. Familiar with mainstream databases. In fact, some really big projects are made by someone specializing in the database, but often many projects require that you, as a (senior) engineer, also participate in the design of the database and the writing of SQL. Therefore, in order to
better contribute to the country, it is recommended that you learn more about some mainstream databases, such as SQLSERVER, ORACLE, multi-connection SQL, stored procedures and triggers. If you are not from a "
class , you also need to add some knowledge of database principles.
Six, proficient in one or two WEBServer.
Because as a JAVA engineer, especially if you
want to become a senior JAVA engineer, you inevitably have to deploy your project to WebServer, and only when you are proficient in a WebServer can you use its
resources to the maximum, which is often Saves a lot of time and effort.
Seven, UML.
You definitely want to be a senior engineer, so it is necessary for you to know or be proficient or proficient in UML, depending on how determined you are to become a senior engineer and project manager. In a more formal development team
, UML is a communication tool for discussing projects. If you want to be a software engineer, you must at least be able to understand it. If you want to be a senior engineer, you must be able to describe your understanding of the project through it. , although this is not required,
it is important.
8. Analyze the problem from a high level:
这不是一个知识点，也不是通过书本就能学得到的。只所以提到这一点，是因为我比您还着急，我希望您更快的成为一个高级的软件工程师，而
不是一个一般的软件工程师。希望您在工作中多向您的系统分析员、需求分析员、系统设计员学习，多站在他们角度上去看您在开发的项目。在最好在项目之初先在
您的脑海里对项目有个大致的分析、设计，然后和他们进行比较，找找差别，想想缺点。
九、 工具。
您在这个阶段可能接触到不同的工具了，尽管您还需要使用JB或者IDEA，但能可能对
ROSE，Together要多了解一些，因为您要画UML了。不要再对Dreamweaver等HTML编辑器情有独钟了，那些JSP页面让初级程序员去写吧
