Linux 64-bit installation instructions. Java other flavors of Linux see Java for Ubuntu, Java for Fedora Follow these steps to download and install Java for Linux.

Three Methods: This tutorial will cover the installation of 32-bit and 64-bit Oracle Java 7 (currently version number 1.7.045) JDK/JRE on 32-bit and 64-bit Ubuntu operating systems. These instructions will also work on Debian and Linux Mint. If you already have Oracle Java 7 installed on your system but need to upgrade then use this method:. For those who only want to install Oracle Java JRE for running Java applications and not to develop Java programs use this method:. For those who want to install Oracle Java JDK to develop Java programs and applications (the Oracle Java JRE is also included in the Oracle JDK) use this method:. Also to enable/upgrade the Oracle Java in your web browsers:. Check if you have Java installed on your system.

To do this, you will have to run the Java version command from terminal. Open up a terminal and enter the following command:. Type/Copy/Paste: java -version. If you have OpenJDK installed on your system it may look like this:. java version '1.7.015' OpenJDK Runtime Environment (IcedTea6 1.10pre) (7b15pre1-0lucid1) OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode). If you have OpenJDK installed on your system, you have the wrong vendor version of Java installed for this exercise.

Completely remove the OpenJDK/JRE from your system and create a directory to hold your Oracle Java JDK/JRE binaries. This will prevent system conflicts and confusion between different vendor versions of Java. For example, if you have the OpenJDK/JRE installed on your system, you can remove it by typing the following at the command line:. Type/Copy/Paste: sudo apt-get purge openjdk-. This command will completely remove OpenJDK/JRE from your system.

Type/Copy/Paste: sudo mkdir -p /usr/local/java. This command will create a directory to hold your Oracle Java JDK and JRE binaries. Make sure you select the correct compressed binaries for your system architecture 32-bit or 64-bit (which end in tar.gz). For example, if you are on Ubuntu Linux 32-bit operating system download 32-bit Oracle Java binaries. For example, if you are on Ubuntu Linux 64-bit operating system download 64-bit Oracle Java binaries. Optional,.

Select jdk-7u40-apidocs.zip. Important Information: 64-bit Oracle Java binaries do not work on 32-bit Ubuntu Linux operating systems, you will receive multiple system error messages, if you attempt to install 64-bit Oracle Java on 32-bit Ubuntu Linux.

Referring to question, How to install 'Open JDK' (Java developement kit) in Ubuntu (Linux)?. Open Terminal from Application Dash or press Ctrl+ Alt+ T. Update repository: sudo add-apt-repository ppa:openjdk-r/ppa sudo apt-get update.

Run the following command in Terminal: sudo apt-get install openjdk-8-jdk sudo apt-get install openjdk-8-source #this is optional, the jdk source code. Type commandline as below.

Apt-cache search jdk (Note: openjdk-8-jdk is symbolically used here. You can choose the JDK version as per your requirement.). For 'JAVAHOME' (Environment Variable) type command as shown below, in 'Terminal' using your installation path. Export JAVAHOME=/usr/lib/jvm/java-8-openjdk (Note: '/usr/lib/jvm/java-8-openjdk' is symbolically used here just for demostration. You should use your path as per your installation.).

For 'PATH' (Environment Variable) type command as shown below, in 'Terminal' using your installation path. 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 1.7.013;. 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 JAVAHOME=/usr/local/jdk1.7.013 export PATH=$PATH:$JAVAHOME/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. 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 jdk1.7.003/. /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. JAVAHOME=/usr/lib/jvm/jdk1.7.0 PATH=$PATH:$HOME/bin:$JAVAHOME/bin export JAVAHOME export PATH Source. 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 default method (repository without external PPAs) in Ubuntu 12.10+ for Oracle's JDK - will try to describe it. install: sudo apt-get install java-package.

download Oracle JDK from. make debian package from downloaded.tar.gz archive: make-jpkg jdk-YOURVERSION-linux-PLATFORM.tar.gz this command will produce.deb package. install package with your favourite way (for example, sudo dpkg -i oracle-java8-jdk8u40amd64.deb) It's officially supported way from debian developers for installing Oracle JDK, and I suppose it's very simple. Installing Java 8 on Ubuntu First you need to add webupd8team Java PPA repository in your system and install Oracle Java 8 using following set of commands. $ sudo add-apt-repository ppa:webupd8team/java $ sudo apt-get update $ sudo apt-get install oracle-java8-installer Verify Installed Java Version After successfully installing oracle Java using above step verify installed version using following command. $ java -version java version '1.8.077' Java(TM) SE Runtime Environment (build 1.8.077-b03) Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode) Configuring Java Environment In Webupd8 ppa repository also providing a package to set environment variables, Install this package using following command.

$ sudo apt-get install oracle-java8-set-default. For Ubuntu 10.04 LTS, the sun-java6 packages have been dropped from the Multiverse section of the Ubuntu archive.

It is recommended that you use openjdk-6 instead. 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 lucid partner' sudo apt-get update sudo apt-get install sun-java6-jre sun-java6-plugin sudo update-alternatives -config java For Ubuntu 10.10, the sun-java6 packages have been dropped from the Multiverse section of the Ubuntu archive. It is recommended that you use openjdk-6 instead. 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 JAVAHOME 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/jdk1.8.020 /usr/lib/jvm/oraclejdk8 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/oraclejdk8 export J2REDIR=/usr/lib/jvm/oraclejdk8/jre export PATH=$PATH:/usr/lib/jvm/oraclejdk8/bin:/usr/lib/jvm/oraclejdk8/db/bin:/usr/lib/jvm/oraclejdk8/jre/bin export JAVAHOME=/usr/lib/jvm/oraclejdk8 export DERBYHOME=/usr/lib/jvm/oraclejdk8/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. You can install via apt-get: sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java9-installer also via manually su - echo 'deb trusty main' tee /etc/apt/sources.list.d/webupd8team-java.list echo 'deb-src trusty main' tee -a /etc/apt/sources.list.d/webupd8team-java.list apt-key adv -keyserver hkp://keyserver.ubuntu.com:80 -recv-keys EEA14886 apt-get update apt-get install oracle-java9-installer exit after do not forget check version java -version.
