- 从控制台模式程序开始（没有花哨的图形，没有鼠标）

- 学习调试器（一种令人难以置信的学习工具）

To become a 'Java programmer', you need to become a programmer, and there is much more than learning a language.
Advices:
- Start with tiny/useless projects, the purpose is to learn programming, not doing something useful.
- Start with console mode programs (no fancy graphics, no mouse)
- Learn debugger (an incredible learning tool)

- A problem ? Google is your friend.
- Learn one or more analyze methods, E.W. Djikstra/N. Wirth Stepwize Refinement/top-Down method is a good start.

和所有这些问题一样：它取决于。这取决于你想做什么，你所在的职位空缺，以及这些工作要求的确切技能。所以做一些研究然后继续你的下一个学习任务，以确保你遵循一条有价值的道路。



一旦你学会了一些你需要练习的东西，练习，练习。

As with all such questions: "it depends". It depends what you want to do, what job vacancies there are in your location, and exactly what skills those jobs are asking for. So do some research before going on with your next learning assignment to make sure you are following a worthwhile path.

And once you have learned something you need to practice, practice, practice.

感谢您的回复。实际上我打算做以下事情：

数据库

移动应用程序（android）。

那么究竟我需要学习什么在这些领域取得成功。

Thanks for your responses. Actually I plan to work on the following things:
Database
Mobile Applications (android).
So what exactly do I need to learn to become successful in those areas.
