installing JDK 8 on ubuntu 15.10

Question

Hello everyone I have JDK 8 installation file but I don,t know how to install it offline. could you help me?

Answer 1

Assuming you have the installation file in .rpm format(that oracle jdk ships with)

sudo apt-get install alien
alien <filename>.rpm
dpkg -i <filename>.deb

Note - Alien is the a package that converts rpm to deb

Or what I would actually suggest you to do is

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

And follow the onscreen instructions. 'Strikingly simple' of-course

Sorry, you asked for offline instructions
