As mention above, most of the source files can be found by downloading the SDK. However for some classes you can find the source code (javax.ssl etc') for I suggest adding the jad eclipse plugin that will decompile any class without using external site such as Docjar.

如上所述，大多数源文件可以通过下载 SDK 找到。但是，对于某些类，您可以找到源代码（javax.ssl 等），因为我建议添加 jad eclipse 插件，该插件将在不使用外部站点（例如 Docjar）的情况下反编译任何类。Jad eclipse 信息：http: //jadclipse.sourceforge.net/wiki/index.php/Main_Page

Here's the browsable source code for OpenJDK 7.
Update: As of June 2018 grepcode seems to be down. Here you can find an alternative.

There is also grepcode.com (not sure how old this site is, perhaps this answer is an update for new solutions now), sample query:
还有grepcode.com（不知道这个网站有多老，也许这个答案现在是新解决方案的更新），示例查询：

You can directly browse the code online here for Java : https://zgrepcode.com/java/openjdk/10.0.2/
您可以直接在此处在线浏览 Java 代码：https: //zgrepcode.com/java/openjdk/10.0.2/
It is a great tool also for browsing most of the open source projects as it gives you internal linking to classes.
它也是浏览大多数开源项目的绝佳工具，因为它为您提供了到类的内部链接。
