Java SE 8 contains new features and enhancements in many functional areas. We point you to the download page on the Oracle website, for legal reasons. The Java SE 8 downloads require you to agree to the license agreement before downloading. Unless you exclusively use 64-bit browsers, you should also install the 32-bit version. Once installed, Java will run unobtrusively in the background, only popping up when an update is released – at most other times it’s invisible, even when being used. Just click the link above for your platform to download the very latest build on your computer, and you should find the previously misbehaving application works properly again. Should you ever find yourself confronted by this message, you’ll need this, the Java Runtime Environment (JRE), which consists of everything you need to run Java through your web browser and – through the bundled Java Virtual Machine – applications on your computer. You might be surprised to discover which applications require Java – often, they’ll automatically bundle and install it automatically during the setup process, but sometimes it doesn’t quite go to plan, and all you’ll be told is that you need Java. It’s also extensively used on various websites, so all-in-all it’s worth installing even as an insurance policy. What makes Java so popular? Its cross-platform for starters, so if you code an application in Java, it’ll run on any computer – Windows, Mac or Linux – that has Java installed. Windows and Linux users will need to install it separately. A very long time ago, it was even installed as part of Windows, but some legal shenanigans later, and now only Apple users have it installed alongside the operating system. Over three billion devices use it, including – of course – computers. If you don't want to set it as default, remove both oracle-java8-installer and oracle-java8-set-default packages, and then install oracle-java8-installer with "-no-install-recommends" (like mentioned above).Java is so ubiquitous it’s almost an essential part of computing life. Note: removing the oracle-java8-set-default package does not undo all the changes (I have yet to find a way to do this properly). Sudo apt-get install -no-install-recommends oracle-java8-installer If you don't want to make Oracle Java 8 default (it might still be set as default, depending on what other Java versions you may have installed), install the oracle-java8-installer with "-no-install-recommends": Sudo apt-get install oracle-java8-set-default So, if you want to set Oracle Java 8 as default, no matter what other Java versions are installed, make sure that you install the oracle-java8-set-default package (which, again, should be automatically installed with the main Oracle Java Installer package in Ubuntu, but not in Linux Mint): In Linux Mint on the other hand, recommended packages are not installed by default, so you must install this package manually if you want to set Oracle Java 8 as default. To make Java 8 default, you must install the "oracle-java8-set-default" package (which configures the Java environment variables and sets it as default), which I added as a "Recommended" package to "oracle-java8-installer".įor instance, in Ubuntu, recommended packages are automatically installed, so "oracle-java8-set-default" should be installed when installing "oracle-java8-installer". The oracle-java8-installer package now sets the Java priority to 1081, and that may or may not set it as default, depending on other Java packages you may have installed (for instance, if Java 7 is also installed, Java 8 becomes default, but if Java 9 is installed, Java 8 doesn't become default). Previously, this package would increment the Java priority to make it default.
