Installation on Linux

Installation of the JDK on Linux is easy and straightforward using apt-get:

1. Update the package index of your computer. From your terminal, run:

 sudo apt-get update

2. Check whether Java is already installed by running the following:

 java -version

3. You'll know Java is installed if the version information for a Java install on your system is printed. If no version is currently installed, run:

 sudo apt-get install default-jdk

That's it! The JDK will be installed on your computer.
