mkdir if not present "/usr/lib/jvm" download package and type this comand from the download directory
tar -zxf jdk-8u5-linux-x64.tar.gz -C /usr/lib/jvm/jdk1.8.0_45
install java
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.8.0_45/bin/java 100
to check if java is installed type
java -version
if you have multiple java you need to configure it by
sudo update-alternatives --config java
enter the number you want the default java to be from the list

The easiest way to install Oracle java to Ubuntu is this. Run
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
You will get latest java 8.

You can't add a repository unless you setup apt to work through proxy. And please ask another question, do not comment here. – Pilot6 Sep 07 '15 at 14:13
