How To Install Java 10 On Ubuntu

In this post, we will discuss all the steps required to install Java 10 distributed by Oracle on Ubuntu 18.04 (Bionic Beaver). The steps should be similar to other releases of Java, Ubuntu and other flavors of Linux.


Step 1 Download JDK


Open the browser and search for Download JDK 10 or click here to open the download page. It will show the JDK download page as shown in Fig. 1.

Now click the download link having tar.gz extension as highlighted in Fig 1. A confirmation dialog will be displayed to accept the license agreement and start the download as shown in Fig.2 and Fig. 3.

We can also download the JDK on terminal using below mentioned command:


>sudo wget -c --header "Cookie: oraclelicense=accept-securebackup-cookie"


Step 2 Install Java


Open the terminal and make directory /usr/java to keep java installations. We can install multiple versions of Java in this directory. Now copy the downloaded file to this location and extract it as shown below:


>sudo mkdir /usr/java
>cd /usr/java
>sudo cp  jdk-10.0.2_linux-x64_bin.tar.gz
>sudo tar -xzvf jdk-10.0.2_linux-x64_bin.tar.gz


The above steps will install JDK to the path /usr/java/jdk-10.0.2


Step 3 Set Environment Variables


>sudo nano /etc/profile


Scroll down by pressing Page Down button and add at the end of this file:


export JAVA_HOME
export PATH


Now press Ctrl + O and press Enter to write our change. Press Ctrl + X to exit the nano editor. The nano editor should look like the one shown in Fig. 4.

Step 4 Configure Java Commands


Now we need to configure Java commands to newly installed JDK. We can check the installed Java before and after executing these commands as shown below:


>java -version
>sudo update-alternatives --install "/usr/bin/java" "java" "/usr/java/jdk-10.0.2/bin/java" 1
>sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/java/jdk-10.0.2/bin/javac" 1
>sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/java/jdk-10.0.2/bin/javaws" 1
>java -version


The output of these commands is displayed on Fig. 5.
