It really depends on people and also depends on what kind of job you will be doing. But let me take a guess from scratch for the time duration to be qualified for a Java software developer.

- Having a very good understanding of the computer systems. (4 years +)
Because we have all gone through the college life and it took us 4 years minimum to systematically learn about computers. To become a master or doctor takes longer time of course.

- Having a very good understanding of the Object-oriented design principle. (1 year +)
The core idea of OOP, which is inheritance, encapsulation, polymorphisms. This requires you to have some coding experience as well.

- Have a strong knowledge of J2SE programming skills. (2 years +)
Have you familiar with most of the critical JAVA API? I expect to hear people asking "Really, 2 years plus to understand j2se? Too long, I can learn them in 21 days." Again, this really depends on people's skill, but from a novice, this time is still a little bit short. And per my own experience, I really wonder the skills of those people who mastered Java in 21 days.

- Understand appropriate software engineering approach. (n years +)
I know some very good software engineers who are really talented but do not adapt any of the right engineering approaches. They refuse to estimate the timeframe at first, they don't like to write any unit tests in the middle of the development. They refuse the meet the deadline because of the requirement changes, etc. And sadly at the end, this results the failure of the software system. Software engineering is really something you cannot learn from text book but practice.

- Having a good understanding of the J2EE architecture. (3 years +)
Very important if you are doing J2EE development. This is a huge topic and I would like some other experts to give more comments here. The J2EE I mean here covers other J2EE-compliant framework like Spring Framework, EJB framework, or other web development frameworks.

- Having a thorough understanding of the database development. (2 years +)
e.g. Database management system, SQL, JDBC, Hibernate etc. Very very important topic in the real business. I know every company has to have at least one database expert. However, all should also be familiar with the database operations.

- To be talented and really strong communication skills and good English. (X years)
Well, we can teach you to study Java but we can not teach you to be clever. This is not something you can learn from textbook again, so I put x years here. Because some people will never be clever.

- To keep a passion for learning new technologies. (xyz years)
The essence of a good software developer or architect should keep an eye on the new technologies and always want to make their hands dirty in the code. I added this one because if you are stick to what you have learned so far and do not want to learn new stuff, then the upshot of that is you will probably be replaced by some new guy.

These are the list I can think at this stage. I might add more points into this list. And I may also make some mistakes in this list, so correct me if I was wrong or you have a different idea or timeframe in the list.

Regards,
Jiafan

我的英语水平只能看个大概，
- Having a very good understanding of the Object-oriented design principle. (1 year +)
- Have a strong knowledge of J2SE programming skills. (2 years +)
我想我暂时的目标也就这样了，尽快理解并掌握面向对象的导向设计原理，和能够写出一些健壮的J2SE程序设计
以后希望您可以帮帮我

Posted by: aiyuaichou Posted on: 2008-06-06 22:46 学JAVA真的要求英语水平很高吗？也许这个水平很高用词有些不合适，但我想知道，究竟需要什么英语水平，短期内如何提高，我想再去学英语，可能有点不现实，有捷径吗？

No, there is no shortcut for learning English. As a general thing, I think if one can read and write a very good Function Specification for a software project, then he or she has good English.
