My brother got a used laptop for Christmas, but it has a Linux operating system. I have never touched a linux ever, so i am a tad bit lost on where to even start. I would like to install Java on it but i do not understand the terminal stuff. Game websites, facebook, and youtube all work. I am not to sure what else to install. The guy who gave it to him works on computers for a living, and he installed a program like Microsoft word on it. It is an Ubuntu 12.10. Any help would greatly be appreciated.
