Question

I was trying to install JDK on my Ubuntu Server, but was not able to do that. Can anyone help me with this?

Answer 1

In able to install JDK in Ubuntu, follow these steps:

1. Open terminal.

2. Update the repository using these commands:

sudo add-apt-repository ppa:openjdk-r/ppa  # only Ubuntu 17.4 and earlier

sudo apt update

3. After that, install the version which you want, using these commands:

sudo apt install openjdk-8-jdk

sudo apt install openjdk-8-source #this is optional, the jdk source code

4. In able to set JAVA_HOME, use this command with your installation path:

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk
