Where to find Java JDK Source Code

Question

I would like to see what a method in the Java API does  So I want the JDK Source Code  Before I re-installed Linux I had the src zip package with all the official source code in it  I just had to tell Eclipse where this file is and I could see the code  But now I don t have the file anymore     So the question is  Where can I find it

The JDK 1 6 I m currently using on OSX Mountain Lion did not come with a src zip either  and as far as i can tell there is no supported OSX JDK for 1 6 available anymore   So I downloaded the OpenJDK source  using the links from the accepted answer   1   then ran   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      your file names and paths may vary      Associate that src jar 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

The official link no longer offers the original source code  The official link and casual google searches will land you with open jdk  Open jdk causes problems with android build unless the build script files are modified  The original package can be found here   sudo add-apt-repository  deb http   ppa launchpad net ferramroberto java ubuntu oneiric main   This repo still has the sun-java6-source package  Credit  http   pulasthisupun blogspot com 2012 05 installing-sun-java-6-with-apt-get-in html

Sadly  as of this writing  DESPITE their own documentation readme  there is no src zip in the JDK 7 or 8 install directories when you download the Windows version   Note  perhaps this happens because many of us don t actually run the install  exe  but instead extract it   Many of us don t run the Java install  the full blown windows install  for security reasons    we just want the JDK put someplace out of the way where potential viruses cannot find it   But their policy regarding the windows  exe  whatever it truly is  is indeed nuts  HOWEVER  the src zip DOES exist in the linux install  a  tar gz    There are multiple ways of extracting a  tar and a  gz  and I prefer the free  7Zip  utility    download the Linux 64 bit  tar gz use 7zip to uncompress the  tar gz to a  tar use 7zip to extract the  tar to the installation directory src zip will be waiting for you in that installation directory  pull it out and place it where you like    Oracle  this is really beyond stupid

You haven t said which version you want  but an archive of the JDK 8 source code can be downloaded here  along with JDK 7 and JDK 6   Additionally you can browse or clone the Mercurial repositories  8  7  6

Chances that you already got the source code with the JDK  it is matter of finding where it is  In case  JDK folder doesn t contain the source code   sudo apt-get install openjdk-7-source   OSX Folks  search in homebrew formulas   In ubuntu  the command above would put your souce file under       usr lib jvm openjdk-7   Good news is that Eclipse will take you there already  How to bind Eclipse to the Java source code    Follow the orange buttons

In JDK 8 source can be found in  src zip  Now in some intermediate releases this zip was missing but again it is available   make sure that you select source as well from installation wizard

This file is contained in the standard JDK download  Also your Linux system probably have JDK in the repository  In my Ubuntu Linux file is located here   usr lib jvm java-6-sun-1 6 0 20 src zip
