Hello LInux Geeksters. Along with the release of the Oracle Java 8, also the NetBeans IDE 8.0 has been receleased. For information about this release, see the changelog for yourselves. 
In this article I will show you how to install NetBeans IDE 8.0 on Ubuntu 14.04 Trusty Tahr, Ubuntu 13.10 Saucy Salamander, Ubuntu 12.10 Quantal Quetzal, Ubuntu 12.04 Precise Pangolin, Linux Mint 17 Qiana, Linux Mint 16 Petra, Linux Mint 14 Nadia, Linux Mint 13 Maya, Elementary OS 0.2 Luna, Debian and their derivative systems.
First, we have to install the Oracle Java 8. For Ubuntu, Linux Mint and Elementary OS, it is available via PPA, so all you have to do is:
$ $ sudo apt-get purge openjdk*
$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java8-installer
Due to the fact that Debian does not have support for PPAs, we have to use it as a simple repository.

$ echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" | tee -a /etc/apt/sources.list
