Java is one of the world's best known programming languages. This practical tip shows you how to install and set up Java on Debian.

Install Java on Debian - Here's how

Before you can actually start installing Java, you must first run the "sudo apt-get update" command and the "sudo apt-get install default-jdk" command (without the quotation marks).

• Also use the "sudo apt-get install software-properties-common" command to install the software properties common package.
• You should then use the sudo add-apt-repository "deb //ppa.launchpad.net/webupd8team/java/ubuntu xenial main" command to ensure that the required repository is available.
• Then update your system again with the command "sudo apt-get update".
• You can now easily install Java with the command "sudo apt-get install oracle-java9-installer".

In the following we would like to show you how to set up Java correctly on your Debian system:

• It is also very important to create the "JAVA_HOME" environment variable: To do this, execute the "sudo nano / etc / environment" command and add the line "JAVA_HOME =" / usr / lib / jvm / java-9- to the end of the file oracle ".
• Note: The path to your Java installation may differ slightly.
