Install the JDK. The sources for the public classes are packaged in src.zip.

I already found the code on Google Code Search, but out of curiosity is this only true for OpenJDK? I'm running Ubuntu and can't find it in the sun-java6-jdk directory. – Matt Robertson Jan 08 '11 at 22:42
Ubuntu repackages everything. Have you installed sun-java6-source? – Thorbjørn Ravn Andersen Jan 08 '11 at 22:57
It is true with the JDK 7 directly from Oracle as well. +1 for being by far the most correct answer here, and saving me decaminutes of time. – le3th4x0rbot Mar 27 '13 at 20:45

OpenJDK code: Browse here
For example, if you looking for AWTUtilities.java, go here in the above link:

src› share› classes› com› sun› awt› AWTUtilities.java

OpenJDK project homepage where they have all the instructions of downloading and building it
OpenJDK Mercurial Repo hosted here
JDK Documentation here

If you only need to look up some classes, the following page is also a good source:

It works for different versions of various libraries.
