How to Install Java on Linux Lite

[Valtam]

Install Java on Linux Lite - this tutorial will show you how to install Oracle's Java on Linux Lite. You must uninstall the openjdk java on Linux Lite first to have your system recognize and use Oracle's Java. Go into Synaptic package manager and remove packages labeled as 'openjdk' there will be only 2. An example of why people may want to use Oracle's Java over OpenJdk's Java is that they find Minecraft will only run under Oracle's or runs better under Oracle's Java.

NB: Best practice is to use only one type of Java on your system at a time. Yes, you can use symlinks, but this OS is for new folk to linux so we're keeping this very simple.

1. Download Java: 32bit or 64bit depending on your system - https://www.java.com/en/download/linux_manual.jsp



2. Open a terminal where the download is and enter:

Code:

sudo su

Code:

mkdir /usr/lib/jvm/oracle_jdk8

Code:

tar -zxvf jre-* -C /usr/lib/jvm/oracle_jdk8 --strip-components=1

Code:

touch /etc/profile.d/oraclejdk.sh

Code:

leafpad /etc/profile.d/oraclejdk.sh

copy and paste the following into the file, then save and close it:

Code:

export J2SDKDIR=/usr/lib/jvm/oracle_jdk8
export J2REDIR=/usr/lib/jvm/oracle_jdk8/jre
export PATH=$PATH:/usr/lib/jvm/oracle_jdk8/bin:/usr/lib/jvm/oracle_jdk8/db/bin:/usr/lib/jvm/oracle_jdk8/jre/bin
export JAVA_HOME=/usr/lib/jvm/oracle_jdk8
export DERBY_HOME=/usr/lib/jvm/oracle_jdk8/db

In the same terminal type, exit.

Now enter:

Code:

source /etc/profile.d/oraclejdk.sh

Do:

Code:

java -version

in a terminal to confirm you have Oracle's Java installed.

Code:

jerry@jerry-VirtualBox:~$ java -version
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) Server VM (build 25.66-b17, mixed mode)
jerry@jerry-VirtualBox:~$

I would like to add this webpage that I found that could make it a bit easier to install the Java JRE

https://www.digitalocean.com/community/t...th-apt-get

I appreciate it when installers exist to make my LL experience more FUNNER!

Code:

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

It starts an installer. The page also has other versions

how do I uninstall java

How can I uninstall Java as I do not need it anymore?

[avj]

If you know which packages were installed, they can be removed from: Install/Remove Software. Make sure to only remove what you installed as some java packages may have been installed by default, and removing them may cause system problems.

[liamjake05]

Not OpenJDK but Oracle's

We need to know how you installed it in the first place.

Go up to the first post exactly like it. Same commands and everything.
