The JDK 1.6 I'm currently using on <a href="https://en.wikipedia.org/wiki/OS_X_Mountain_Lion" rel="nofollow noreferrer">OS X v10.8</a> (Mountain Lion) did not come with a <code>src.zip</code> either, and as far as I can tell there is no supported Mac OS X JDK for 1.6 available anymore.
So I downloaded the OpenJDK source (using the links from the accepted answer (+1)) then ran:
<pre class="lang-none prettyprint-override"><code>cd ~/Downloads
mkdir jdk6src
cd jdk6src
tar xf ../openjdk-6-src-b27-26_oct_2012.tar.gz
cd jdk/src/share/classes
jar cf /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/src.jar *
</code></pre>
(Your file names and paths may vary...)
Associate that <code>src.jar</code> with the appropriate Java platform in your IDE and you should be good to go.
There are some discrepancies between the OpenJDK source and the JDK I'm currently running (line numbers don't match up in the debugger, for one), but if all you want is a zip/jar to point your IDE to for the relatively few cases you need to peek at some code to understand how something works, then this should do the trick.

Chances that you already got the source code with the JDK, is a matter of finding where it is. In that case, the JDK folder doesn't contain the source code:
<pre class="lang-none prettyprint-override"><code>sudo apt-get install openjdk-7-source
</code></pre>
OS X folks, search in <a href="https://en.wikipedia.org/wiki/Homebrew_(package_manager)" rel="nofollow noreferrer">Homebrew</a> formulas.
In Ubuntu, the command above would put your source file under:
<pre class="lang-none prettyprint-override"><code>/usr/lib/jvm/openjdk-7/
</code></pre>
The good news is that Eclipse will take you there already (how to bind Eclipse to the Java source code):

Well, I opened terminal in my Mac and typed:
<pre><code>echo $JAVA_HOME
</code></pre>
Then I got the directory, went there and found src.zip.

I would like to see what a method in the Java API does. So I want the JDK source code.
Before I reinstalled Linux I had the <code>src.zip</code> package with all the official source code in it. I just had to tell <a href="https://en.wikipedia.org/wiki/Eclipse_%28software%29" rel="nofollow noreferrer">Eclipse</a> where this file is and I could see the code. But now I don't have the file anymore...
Where can I find it?

Where can I find the Java JDK source code?

集成开发环境

调试器

Eclipse

Ubuntu

Linux

Java

我想看看Java API中的方法是做什么的。所以我想要JDK的源代码。在我重装Linux之前，我有一个包含所有官方源代码的src.zip包。我只需要告诉这个文件在哪里，我就可以看到代码了。但现在我没有文件了..。我在哪里可以找到它？
