Today we are going to learn that how to install Java 14 on Ubuntu 18.04. As Java is the most popular programming language to develop different types of Android, Web and other business applications. It is also used in developing the games and other such projects. Java 14 is now available and you can find the new features in this by visiting the official release page of Java 14 to view interesting features. So, let’s move towards the installation of the Java on our Ubuntu system.
Here are some methods that we’ll use to install Java on our system.
- By installing Oracle Java SE Development Kit 14
- Installing from PPA Repository
- By installing manually
We will cover all of these methods so you can install easily by choosing your preferred one.
Step 1: Installing Oracle Java SE Development Kit 14
You can download the Debian package of Java 14 at Java SE Development Kit official page. If you want to download it manually, simply run the command with wget & curl.
So, as usual we do, update your system and install wget and curl.
sudo apt update
sudo apt -y install wget curl
After installing these, pull the Java SE Development Kit 14 Debian package by running the below command.
wget --no-check-certificate -c --header "Cookie: oraclelicense=accept-securebackup-cookie" "https://download.oracle.com/otn-pub/java/jdk/14+36/076bab302c7b4508975440c56f6cc26a/jdk-14_linux-x64_bin.deb"
Output:
jdk-14_linux-x64_ 100%[=============>] 157.91M 955KB/s in 3m 14s

Now, with the help of apt install the DEB package by typing
sudo apt install ./jdk-14_linux-x64_bin.deb
And then press Y when prompted to continue. You’ll see the similar output on successful installation.
sudo apt install ./jdk-14_linux-x64_bin.deb

After it set the Java Environment Variables to use it in command line operation.
cat <<EOF | sudo tee /etc/profile.d/jdk14.sh
export JAVA_HOME=/usr/lib/jvm/jdk-14
export PATH=$PATH:$JAVA_HOME/bin
EOF
Now, source the file by
source /etc/profile.d/jdk14.sh
Then verify the installation by running java -version command.
Output:
sabi@Ubuntu-18:~$ java -version
java version "14" 2020-03-17
Java(TM) SE Runtime Environment (build 14+36-1461)
Java HotSpot(TM) 64-Bit Server VM (build 14+36-1461, mixed mode, sharing)
Step 2:Installing Java 14 from PPA Repository
In first step we installed the Java by using Java 14 SE Development Kit. Now, we will use the PPA repository to install Java 14 on our system. As the Java binaries are being available on the PPA repository, so we’ll add the repo with the help of given command.
sudo apt update
sudo add-apt-repository ppa:linuxuprising/java
Then install the Oracle Java 14 using the below command
sudo apt -y install oracle-java14-installer
Then accept the licence, and digital technology license agreement when prompted.
You can also set it to the default by installing the following package.
sudo apt -y install oracle-java14-set-default
Verify the installation by running the java -version command
java -version
After it set up the Java Environment Variables.
sudo nano /etc/profile.d/jdk.sh
export JAVA_HOME=/usr/lib/jvm/java-14-oracle
export PATH=$PATH:$JAVA_HOME/bin
Now, source the file
source /etc/profile.d/jdk.sh
Step 3: Installing Java 14 Manually
Install the Java 14 manually using the curl command. You can also download the package from the download page.
curl -O https://download.java.net/java/GA/jdk14/076bab302c7b4508975440c56f6cc26a/36/GPL/openjdk-14_linux-x64_bin.tar.gz
Once the package is downloaded, extract it
tar xvf openjdk-14_linux-x64_bin.tar.gz
Then move the output to the /opt directory
sudo mv jdk-14 /opt/
And after it set up the Java environment.
sudo tee /etc/profile.d/jdk14.sh <<EOF
export JAVA_HOME=/opt/jdk-14
export PATH=$PATH:$JAVA_HOME/bin
EOF
Then source the file.
source /etc/profile.d/jdk14.sh
Verify the installtion
$ echo $JAVA_HOME
/opt/jdk-14
$ java -version
openjdk version "14" 2020-03-30
OpenJDK Runtime Environment (build 14+36-1461)
OpenJDK 64-Bit Server VM (build 14+36-1461, mixed mode, sharing)
So, this is how you can Install the Java on your Ubuntu/Debian system or server.
