Answer 1

Download Java SE 7u4 from Oracle. (This is 64-bit only)

This installs to /Library/Java/JavaVirtualMachines/1.7.0.jdk.

However, when you run java -version it will still output 1.6 or some other old version. Follow the readme directions below:

Open Java Preferences in /Applications/Utilities. Drag Java SE 7 to the top. It will now be your default JVM. Run java -version again, and you should see something like:

java version "1.7.0_04"
Java(TM) SE Runtime Environment (build 1.7.0_04-bxx)
Java HotSpot(TM) 64-Bit Server VM (build 23.0-b17, mixed mode)

Once this is complete, a new install of Eclipse should select JDK7 by default. Otherwise:

1. go to Eclipse->Preferences...->Java->Installed JREs
2. click Add...
3. Select Standard VM
4. paste /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home into JRE home
5. Change the JRE name to something useful like Java SE 7
6. Click Finish
7. Check the checkbox next to your newly created JRE.

Answer 2

Make sure that you aren't setting JAVA_HOME in your .bash_profile, otherwise this may prevent java -version from returning the desired result.

Answer 3

You just download it here, install it where you like, and include it in your path or select that JDK in your IDE
