Macro aspects
I. JAVA.
To become a JAVA (senior) engineer definitely need to learn JAVA. general programmers may only need to know some of the syntactic structure of JAVA can cope with. But to become a JAVA (Advanced)
engineer, you need to do a more in-depth study of JAVA. You should study JDBC, IO packages, Util packages, Text packages, JMS, EJB, RMI, threads. If possible, I hope you
JAVA all packages are browsed, know the general API, so you will find that in fact you want to achieve a lot of functionality through the JAVA API can be achieved, you do not have to spend too much of their own brain.
Two, design patterns.
In fact, writing code is a very easy thing, I believe you have the same feeling. But how to write well is more difficult. The word "good" includes code reusability, maintainability, and extensibility. How to write good code
Code is often based on design patterns. Of course, the long-term experience of code accumulation, as long as you pay attention, will enable you to form their own code style. I believe that your code is also more in line with the reusability, maintainability, and extensibility of the code.
But since our predecessors have already given us their experience, why don't we step on their shoulders and move forward?
Three, XML.
Nowadays, it is almost impossible not to use XML in the system. XML is very powerful, it can do data conversion, do the configuration of the system, and even save your system business data. So you need to understand
XML, including its syntax, structure. You also need to be more proficient in the use of parsing XML of some APIs, such as JDOM, SAX, etc., because in our general project, XML often plays the role of system configuration
Information, you need to use these APIs to parse the configuration information, the development of the perfect project.
Four. Proficient in using one or two frameworks.
"Frameworks come with a lot of reusable code, good hierarchical relationships and business control logic, and framework-based development
allows you to save a lot of development costs". Here I hope you can be proficient, more than that, I hope you can understand the idea of frameworks through the use of frameworks. So that you will be in the development of a project when the idea will be open, for example, you
will think of the SQL statement with your JAVA code separately, and then you will consider the configuration of your business logic to the XML or database, so that the whole project is very easy to expand.
V. Familiarize yourself with major databases. In fact, the really big projects are people who specialize in databases, but often many projects require you as a (senior) engineer to participate in the design of the database as well as SQL writing. So in order to
better contribute to the country, it is recommended that you still know more about some mainstream databases, such as SQLSERVER, ORACLE, multi-connection SQL and stored procedures and triggers. If you are not a "class" out of
Body, you also need to add some knowledge of database principles.
Sixth, be proficient in one or two WEBServers.
Because as a JAVA engineer, and especially if you want to become a senior JAVA engineer, you will inevitably have to deploy your project to a WebServer, and only if you are proficient in one WebServer will you be able to maximize its
resources, and this is where you will need to add some additional knowledge. >
Resources, which can often save a lot of time and effort.
VII. UML.
You definitely want to be a senior engineer, so it's necessary for you to understand or be skilled or proficient in UML, depending on how committed you are to becoming a senior engineer and project manager. In more formal development teams
the UML is the communication tool for discussing projects, and for you to be a software engineer you need to be able to at least read it, and for you to be a senior engineer you need to be able to describe your understanding of a project by using it, which, while not required, is
important.
VIII. Analyzing problems from a high level:
This is not a point of knowledge, nor can you learn it through books. Only mention this point, because I am more anxious than you, I hope you faster to become a senior software engineer, and
not a general software engineer. I want you to learn from your system analysts, requirements analysts, and system designers, and to look at the projects you are developing from their point of view. In the best in the beginning of the project first in
Your mind on the project has a general analysis, design, and then and their comparison, to find the differences, think about the shortcomings.
Nine, tools.
You've probably come across different tools at this stage, and although you'll still need to use JB or IDEA, you'll probably want to know more about
ROSE, Together, because you'll be drawing UML. Don't be obsessed with Dreamweaver and other HTML editors, those JSP pages let the junior programmers to write it
