You'll have to adapt the file names a bit, since Java versions have changed, but this Ask Ubuntu Q&A has very extensive installation instructions: How can I install Sun/Oracle's proprietary Java JDK 6/7/8 or JRE?.Īs for default Java version, you need to have the one you want as default installed, and then you need to select it as the default. x86 is named after a line of old Intel CPUs (I think), but they didn't really have anything to name 64-bit after, so it became 圆4. You seem to have a bit of a misunderstanding in regards to 32-bit. It makes it easier for one person to answer.

I apologize for my english and my gnu-ignorance, hoping someone has an answer :) Third, all started because my javac -version gave 1.7 as a result (1.8 is needed), but after downloading the package and doing what they do the commands STILL gives version 1.7, which is mainly why I ask this question. Second, I didn’t saw any bash/python file to '''install''' the package, so is there a special folder to put it or the home will do? First, why is there no 32 bit package downloadable? And can I download the 64 anyway and it works (I mean probably not, but the 32 bit is just not existing.) I did what they tell to do, but I encountered 3 problems:

Now this was in order to install android studio, following the instructions on this page I was trying to update the JDK on my machine (Ubuntu 14) by downloading the packages on Java official site (this one )
