In this tutorial we’ll Install Java 10 on Ubuntu 18.04 LTS, 16.04 LTS (and its forks) using PPA. There are two types of JAVA installation available which are JDK and JRE. JDK (Java Development Kit) provides to develop new Java applications, which includes Java compiler. JRE (Java Runtime Environment) provides the runtime environment for any Java application with applets. The Java development kit requires JDK and JRE both should be installed on the system to create new Java Applications.

Lets Get Started :

STEP 1

Install PPA from https://launchpad.net/~linuxuprising/+archive/ubuntu/java

apt-get install -y software-properties-common
add-apt-repository ppa:linuxuprising/java
apt-get update

STEP 2

Install java 10 via command :

apt-get install oracle-java10-installer

To set Java 10 as default Version run this command :

apt-get install oracle-java10-set-default

Verify the java Version :

java -version 

Output will as follows :

root@mysterydata:~# java -version
java version "10.0.1" 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)

STEP 3 :

Setup JAVA_HOME and JRE_HOME Environment Variable :

It is necessary to add this environment variable in order to run the java apps flawlessly to add run this bash script :

sh /etc/profile.d/jdk.sh

Or do it manually via below commands :

export J2SDKDIR=/usr/lib/jvm/java-10-oracle
export J2REDIR=/usr/lib/jvm/java-10-oracle
export PATH=$PATH:/usr/lib/jvm/java-10-oracle/bin:/usr/lib/jvm/java-10-oracle/db/bin
export JAVA_HOME=/usr/lib/jvm/java-10-oracle
export DERBY_HOME=/usr/lib/jvm/java-10-oracle/db

Thats it java 10 is now successfully installed on Ubuntu(and its forks) systems.
