I'm trying to install Java.

@Compt I need to install Java 7 for my Minecraft server and when I searched on Google for Java 7, a tutorial for doing this came up.

Have you tried with root permissions? You're doing from the terminal? – Lucio Jun 26 '12 at 21:36

From terminal run sudo mv /path/to/file /usr/lib

You may want to elaborate about how this applies to the OP's situation. Remember, the OP is using WinSCP, which is an sftp/scp client for Windows. Also, please note that this only works the folder is on the same partition as /usr/lib--otherwise, if using standard command line tools, one must copy (with cp) and delete (with rm -r, or rmdir for an empty folder) instead. – Eliah Kagan Jun 26 '12 at 23:14

Installing java is easy.

To install the JRE. On the command line, type:

sudo apt-get install openjdk-7-jre


To install the JDK. On the command line, type:

sudo apt-get install openjdk-7-jdk

JRE = Running Java applications

JDK = Developing Java applications

If you need root permissions, type in "sudo nautilus" within the terminal. That will give you access to any folder you need to modify. However, I am curious, why are you trying to install java instead of Open JDK?

Edit: Ahh kk, Minecraft is a pretty sweet game. This answer gives you complete control of your directory, but you'll have to move the folder still.
