I would recommend you to take a look at various open-source projects. As their code is freely available, it tend to be of honorable quality.

To access those sources, you can go on <a href="http://koders.com" rel="nofollow noreferrer">http://koders.com</a> or its alternatives (see as an example <a href="https://stackoverflow.com/questions/818647/where-can-i-find-good-c-source-code">this question on C++</a>)

blocks|key|1447062|text|选择你最喜欢的开源库，开始阅读吧。这将有助于您更深入地理解库的工作原理。这是一个非常好的list+of+open+source+java+libraries。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1447063|然而，我发现自己解决编程问题更有用，然后看看别人是如何解决同样的问题的。Project+Euler是一个做这件事的好地方。这只是我个人的偏好。|1447064|entityMap|0|LINK|mutability|MUTABLE|url|http://java-source.net/|1|http://www.projecteuler.net/^0|18|Y|0|0|10|D|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@$A|U|B|V|1|W]]|C|$]]|$1|F|3|-4|5|6|7|X|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]]]

Pick your favorite open source library and start reading that. This will have the ancillary benefit of helping you gain a deeper understanding of how the library works. Here is a pretty good <a href="http://java-source.net/" rel="nofollow noreferrer">list of open source java libraries</a>.

However, I find it more useful to tackle a programming problem myself, and then afterwords see how others approached the same problem. <a href="http://www.projecteuler.net" rel="nofollow noreferrer">Project Euler</a> is a great place to do this. Just my personal preference.

<a href="http://www.refactoring.com/catalog/index.html" rel="nofollow noreferrer">http://www.refactoring.com/catalog/index.html</a>

Know the Design patterns and when and how to apply them. 

Use static code analysis like PMD or another to point out some issues. 
Do not ignore warnings in your own code.

As an alternative or a starter: Those two books have a good reputation amongst Java programmers and help to make up your mind how good code should look like:

<li>Effective Java (2nd Edition) (Joshua Bloch)</li>
</ol>

Here is another interesting web link to a book that covers code reading: <a href="http://www.spinellis.gr/codereading/" rel="nofollow noreferrer">Code Reading: The Open Source Perspective</a>

An interesting way to train your skills towards good code is exercising <a href="http://codingkata.org/" rel="nofollow noreferrer">coding katas</a>.

blocks|key|2364464|text|我也喜欢浏览Java标准库中的代码。从您实际使用的小方法开始；然后转到String、Integer和其他基本类型等类，然后慢慢地转到整个包，例如Collections包。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2364465|与查看不同的类并弄清楚设计相比，查看一两个方法可能不会丰富体验。|2364466|开源库也不错。选择那些你在日常工作中实际使用的，并且是由你尊敬的程序员/组织开发的。|2364467|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I like to look through the code in Java's standard libraries too. Start off small with the methods that you actually use; then move on to classes like String, Integer, and other basic types, and move on slowly to entire packages, the Collections package, for e.g.

Looking at a method or two, is probably not going to be that enriching an experience compared to looking at different classes and figuring out the design.

Open source libraries are good too. Pick those that you actually use in your daily work and were developed by programmers/organizations you respect.

blocks|key|2364486|text|我已经在Eclipse中安装并集成了Java源代码，所以当我编程并使用Java+API中的某个类时，我可以深入研究该类的源代码，看看某些东西是如何实现的。特别有趣的是与集合和并发相关的类。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2364487|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I have the Java sources installed and integrated in Eclipse, so when I'm programming and I'm using some class from Java's API I can dig into the class' source code and see how some things are implemented.
Particularly interesting are the Collections and Concurrency related classes.

blocks|key|1447219|text|尽管代码可能不合法，但请查看一些MMO+Private服务器的java源代码。它们很棒，因为它们的源代码是开放的、丰富的，并且包含您在玩游戏时可以看到的概念和操作的方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1447220|不过，我并不提倡举办一个，因为这在大多数地区是非法的，但请随意浏览一下作品。|1447221|编辑：|1447222|重要提示:我自己不开发游戏，但它们是理解程序员输入和视觉输出的很好的资源。看看大卫·布拉基恩的书和他网站上的资料。有趣的东西，但不是神圣的。|1447223|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

Although the code may not be legitimate, look at some MMO Private Servers' java source. They're great because the source is open, bountiful, and contains methods to concepts and actions that you can visibly see when playing the game.

I do NOT promote hosting one, though, because that is illegal in most areas, but feel free to glance at the work.

EDIT:

Important note: I don't develop games, myself, but they are great sources to understand programmer input and visual output. Look at David Brackeen's book and sources on his site. Interesting stuff, but not godly.

blocks|key|1447104|text|看看Swing库-它使用了一些设计模式和良好的面向对象设计。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1447105|另外，我曾经阅读过Atlassian+JIRA问题跟踪器的源代码，但你需要特别的许可才能这样做。|1447106|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Take a look to the Swing library - it uses some design patters and good object-oriented design.

Also, I used to read source code of Atlassian JIRA issue tracker, but you need special license to do that.
