I went to the website to download (Java Platform (JDK) 8u20 ),
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
to download ORACLE java for my machine. I was confused which packages are necessary for me.
the command uname -a
shows
Linux xxx 3.13.0-35-generic #62-Ubuntu SMP Fri Aug 15 01:58:42 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Please suggest me what are the packages I should download and install for oracle java.
