Installing Java on Ubuntu using APT

The Oracle JDK is the official JDK; however, it is not provided as default installation for Ubuntu.

You can install the oracle JDK using apt-get, following the next steps:

Add a custom repository:

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update

Install the latest jdk version:

sudo apt-get install oracle-javaX-installer

Note: Replace X with the version number.

Update the current default version:

sudo update-alternatives --config java

sudo update-alternatives --config javac

Update your java home path:

sudo nano /etc/environment

JAVA_HOME="YOUR_PATH"

source /etc/environment

echo $JAVA_HOME

Note: Use the path displayed while updating alternatives.

I wish that I can help someone.
