How do I install Oracle Java JDK 7?

I'm running Ubuntu 12.04

I know this has been asked many times but I just recently switched to linux and I'm having a hard time piecing everything together.

I have Oracle's JDK 7 running just fine from the command prompt but I'm not sure what the best way to install eclipse and maven are so that they will use it.

Last time I tried installing eclipse with apt-get and it ended up installing openjdk6.

How do I go about installing eclipse and maven so that they both are using oracle 7 jdk?

Pre question edit:

You need to:

I think it's a duplicate question, but you combine multiple questions into one. This violates the ask one question at a time component of the FAQ.

Post question edit:
You would need to look at the questions on installing eclipse and set your launcher to use a terminal so your .bashrc variables get applied. An alternate solution would be to set up the environment variables in .profile. A better alternative is to use update alternatives, but this too is covered in the oracle-jdk question.

It's my opinion that it's still a duplicate despite having narrowed scope.

Use the following command to avoid installation of default-jdk in Ubuntu 12.04 i.e openjdk6
$ sudo apt-get --no-install-recommends install eclipse

I guess you have not set the path correctly

After installing openjdk set the path to the oracle jdk...

JAVA_HOME=/usr/local/java/jdk1.7.0_04 PATH=$PATH:$HOME/bin:$JAVA_HOME/bin JAVA_HOME=/usr/local/java/jre1.7.0_04 PATH=$PATH:$HOME/bin:$JAVA_HOME/bin export JAVA_HOME export PATH

you can also get it from the ubuntu software centre, and you can also use openjdk6 or 7, you can easily install that with synaptic software centre (sudo apt-get install synaptic) I got eclipse running just fine.
