#OPENJDK 7 JAVA DESKTOP INSTALL#
sudo apt-get install oracle-java7-installer sudo apt-get install oracle-java6-installer Then, depending on the version you want to install, execute one of the following commands: Oracle JDK 6 Sudo add-apt-repository ppa:webupd8team/java To install any version, first execute the following commands: sudo apt-get install python-software-properties
The Oracle JDK is the official JDK however, it is no longer provided by Oracle as a default installation for Ubuntu. If you instead need the Java Development Kit (JDK), execute the following command: sudo apt-get install openjdk-7-jdk This will install the Java Runtime Environment (JRE). To install OpenJDK 7, execute the following command: sudo apt-get install openjdk-7-jre 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.Īll other steps are optional and must only be executed when needed. 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. If you instead need the Java Development Kit (JDK), which is usually needed to compile Java applications (for example Apache Ant, Apache Maven, Eclipse and IntelliJ IDEA execute the following command: sudo apt-get install default-jdk 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
Then, check if Java is not already installed: java -version

#OPENJDK 7 JAVA DESKTOP HOW TO#
We strongly recommend using the following guide for working with Java on Ubuntu: How To Install Java with Apt-Get on Ubuntu 16.04.
