After installation you can run java -version to check whether Java is installed. Installing OpenJDK 8 • To install OpenJDK 8 run below commands.
Open terminal (Ctrl+Alt+T) and run the command: sudo add-apt-repository ppa:webupd8team/java Type in your password when it asks and hit Enter. Update and install the installer script: Run commands to update system package index and install Java installer script: sudo apt update; sudo apt install oracle-java8-installer You may replace oracle-java8-installer with oracle-java9-installer to install Java 9. While the install process, you have to accept Java license to continue downloading & installing Java binaries. Check the Java version To check the Java version after installing the package, run command: javac -version 4. Set Java environment variables The PPA also contains a package to automatically set Java environment variables, just run command: sudo apt install oracle-java8-set-default For Java 9, install the package oracle-java9-set-default instead.
First, update the package index: sudo apt-get update Then, check if Java is not already installed: java -version If it returns 'The program java can be found in the following packages', Java hasn't been installed yet, so execute the following command: sudo apt-get install default-jre This will install the Java Runtime Environment (JRE). If you instead need the Java Development Kit (JDK), which is usually needed to compile Java applications (for example,, and execute the following command: sudo apt-get install default-jdk The JDK is usually only necessary if you are going to compile Java programs or if your software specifically requires it in addition to Java. Since the JDK contains the JRE, there are no disadvantages if you install the JDK instead of the JRE, except for the larger file size. All other steps are optional and must only be executed when needed. Installing OpenJDK 7 (optional) To install OpenJDK 7, execute the following command: sudo apt-get install openjdk-7-jre This will install the Java Runtime Environment (JRE). If you instead need the Java Development Kit (JDK), execute the following command: sudo apt-get install openjdk-7-jdk Installing Oracle JDK (optional) The Oracle JDK is the official JDK; however, it is no longer provided by Oracle as a default installation for Ubuntu.
Export PATH=$PATH:/usr/lib/jvm/java-8-openjdk/bin (Note: '/usr/lib/jvm/java-8-openjdk' is symbolically used here just for demostration. You should use your path as per your installation.) • Check for 'open jdk' installation, just type command in 'Terminal' as shown below javac -version. You can install Oracle's JDK 1.7 fairly easily too; as an example this is how to install JDK 1.7.0_13; • Download the JDK. The download to the newest version is always linked from. As root, do; cd /usr/local tar xzf As your normal user, add or change these two lines in your ~/.profile to point to the installation; export JAVA_HOME=/usr/local/jdk1.7.0_13 export PATH=$PATH:$JAVA_HOME/bin If it's an update, you may also want to remove the old java installation directory in /usr/local. Log out and in again (or do. ~/.profile), and everything should just work.
• sudo update-alternatives --config java The output will look something like the following. In this case, this is what the output will look like with all Java versions mentioned above installed.

I'm running Kubuntu 18.04 and my fonts are in the latter directory. Nothing exactly breaks explicitly because of this, but it does cause fonts to be messed up, without any real indication as to why.
The downside with Oracle's JDK is that it won't update with the rest of your system like OpenJDK will, so I'd mostly consider it if you're running programs that require it. In case you have already downloaded the ZIP file follow these steps. Run the following command to unzip your file. Tar -xvf ~/Downloads/jdk-7u3-linux-i586.tar.gz sudo mkdir -p /usr/lib/jvm/jdk1.7.0 sudo mv jdk1.7.0_03/* /usr/lib/jvm/jdk1.7.0/ sudo update-alternatives --install '/usr/bin/java' 'java' '/usr/lib/jvm/jdk1.7.0/bin/java' 1 sudo update-alternatives --install '/usr/bin/javac' 'javac' '/usr/lib/jvm/jdk1.7.0/bin/javac' 1 sudo update-alternatives --install '/usr/bin/javaws' 'javaws' '/usr/lib/jvm/jdk1.7.0/bin/javaws' 1 After installation is complete, set environment variables as follows. Edit the system path in file /etc/profile: sudo gedit /etc/profile Add the following lines at the end.
404 Not Found 2018-07-17 22:42:22 ERROR 404: Not Found. Download failed Oracle JDK 10 is NOT installed. Dpkg: error processing package oracle-java10-installer (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: oracle-java10-installer E: Sub-process /usr/bin/dpkg returned an error code (1).
You can do this by executing the same command as in the previous section: • sudo update-alternatives --config java Copy the path from your preferred installation and then open /etc/environment using nano or your favorite text editor. • sudo nano /etc/environment At the end of this file, add the following line, making sure to replace the highlighted path with your own copied path.
If you can not switch from the proprietary Sun JDK/JRE to OpenJDK, you can install sun-java6 packages from the Canonical Partner Repository. You can configure your system to use this repository via command-line: sudo add-apt-repository 'deb maverick partner' sudo apt-get update sudo apt-get install sun-java6-jre sun-java6-plugin sudo update-alternatives --config java. Using a PPA You can use (this will download the required files from Oracle and install JDK 8): sudo apt-add-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java8-installer Also ensure your JAVA_HOME variable has been set to: /usr/lib/jvm/java-8-oracle Manual install The tar.gz provided by Oracle don't have an actual installation process. You just extract those files to a location you want and add them to your path. So the process is the following: Download a.tar.gz from (here I will be using jdk-8u20-linux-x64.tar.gz); Extract it to somewhere; Move the extracted folder to /usr/lib/jvm. This is not required but it is the place where Java runtime software is installed sudo mv /path/to/jdk1.8.0_20 /usr/lib/jvm/oracle_jdk8 Create a file /etc/profile.d/oraclejdk.sh with the following content (adapt the paths to reflect the path where you stored your JDK): 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 Done! Those paths will only be recognized after you logout or restart, so if you want to use them right away run source /etc/profile.d/oraclejdk.sh.
Specifically, this command will install the Java Runtime Environment (JRE). • sudo apt-get install default-jre There is another default Java installation called the JDK (Java Development Kit). The JDK is usually only needed if you are going to compile Java programs or if the software that will use Java specifically requires it. The JDK does contain the JRE, so there are no disadvantages if you install the JDK instead of the JRE, except for the larger file size.
There are two standard types of installation available are JDK and JRE. JDK (Java Development Kit) provides the ability to develop a new Java application, which includes Java compiler. JRE (Java Runtime Environment) provides the runtime environment for any Java application with applets. The Java developers required to install JDK and JRE both on their system to create new Java Applications.
Oracle provides Java 10 for 64bit only, so the packages from the LinuxUprising Java PPA will only work on 64bit. Do not try to use this on other architectures because it won't work!

After adding our Oracle Java PPA to your software sources and installing Java, here's how to make it default. Don't worry though, there's no need to manually run commands like sudo update-alternatives --config java or anything like that. In Ubuntu, Oracle Java 10 should be automatically set as default. Thanks for the package. Why does it conflict with the openjdk java? Sudo apt install openjdk-11-jre Reading package lists. Done Building dependency tree Reading state information.
OpenJDK is OK for the most cases, but Oracle JDK can be required for some bank client applications (my case) - I can't use OpenJDK. I'm surprised that I don't see any answer with the default method (repository without external PPAs) in Ubuntu 12.10+ for Oracle's JDK - I will try to describe it. • Install: sudo apt-get install java-package • Download Oracle JDK from • Make a Debian package from the downloaded.tar.gz archive: make-jpkg jdk-YOUR_VERSION-linux-PLATFORM.tar.gz This command will produce a.deb package.
