Whether you need to run an application or develop one, Oracle Java is must have for any system and that goes same for your Linux machine as well. With that being said, by the end of this easy, step-by-step tutorial you will have Oracle Java fully installed and configured for your Linux machine be it Ubuntu, Debian or Mint. Please note that for the duration of this tutorial i will be using Ubuntu 14.04. Further, where ever possible along with the steps that make use of the terminal, i will also mention alternative methods to execute those same steps, the non-terminal / coding way to help our newbie friends. Now, you are going to be installing either Oracle JDK or Oracle JRE so it’s important to understand the difference between both of them.
Oracle Java Runtime Environment, JRE is the minimum requirement for executing a Java program. It consists of the Java Virtual Machine (JVM), core classes, and supporting files. In short, when you only care about running Java programs on your browser or computer, you will install JRE. See this guide.
Oracle Java Development Kit, JDK is a Software Development Kit for Java which includes the Java Runtime Environment, the JVM and all of the class libraries present in the production environment to create and compile programs so if you are planning to do some Java development, you will need JDK. See this guide on. Removing Open JDK 2.1. In Linux, by default Open JDK is made available which is quite unstable and buggy and hence not recommended for enterprise / commercial application development. As compared to Open JDK, performance and stability is noticeably better on Oracle Java which is why you should remove Open JDK and replace it with Oracle JDK / JRE. Non-Terminal Method Ubuntu users can simply open the Ubuntu Software Centre, search “ OpenJDK“, select the version you installed and click on Remove as depicted in the screenshot below. Copying the tar.gz JRE / JDK files to the /usr/local/java directory In most cases your downloaded JDK / JRE tar.gz files will be downloaded to the home/”username”/Downloads directory. For example: in my case it is home/kross/Downloads where kross is the username. NOTE: You can see that the downloaded files are by default named in a specific way such as jdk-8u5-linux-i586.tar.gz which in this case is a 32 bit JDK version 8u5 file.
In the future, when newer version of java will get released such as 9u45, in such as case do a simple replacement as shown below: 1. For 32 bit JDK file: jdk-9u45-linux-i586.tar.gz 2. For 32 bit JRE file: jre-9u45-linux-i586.tar.gz 3.
For 64 bit JDK file: jdk-9u45-linux-x64.tar.gz 4. For 64 bit JRE file: jre-9u45-linux-x64.tar.gz Similarly, 9u45 is equivalent to 1.9.045 8u5 is equivalent to 1.8.005 8u0 is equivalent to 1.8.000. Editing the system Path file /etc/profile 8.1. Open terminal and type and press enter: sudo gedit /etc/profile. This is opens up a text editor which contains all Linux system wide environment and startup programs. Scroll down to the end of the file and add the following lines below to the end of your /etc/profile file: If you are installing JDK then Copy and Paste the below code. JAVAHOME=/usr/local/java/jdk1.8.005 PATH=$PATH:$HOME/bin:$JAVAHOME/bin JREHOME=/usr/local/java/jdk1.7.005/jre PATH=$PATH:$HOME/bin:$JREHOME/bin export JAVAHOME export JREHOME export PATH.
