Installing Java
Since all DIS2 assignment should be solved using Java, we provide this page with a quick overview of how to install it on all different platforms.Mac
- Checking if your Mac already has a version installed can be done by entering the following command in the terminal:
java -version
If it was already installed you will get a version number and you can stop here.
Otherwise, the command will not have been found meaning there is Java installed yet. In that case, follow the next steps. - Installing Homebrew (a very useful package manager):
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
- Installing Java:
brew cask install java
- You are all set (you can update Java anytime by running
brew update).
Linux
- Open up the commandline and update the package index by running:
sudo apt-get update
- Next, check if you have Java installed:
java -version
If you see a "not found" message, follow the next steps. - To install Java run:
sudo apt-get install default-jre(Java Runtime Environment)
sudo apt-get install default-jdk(Java Development Kit) - You are done.
Windows
- Contrary to the other two platforms, installing Java on windows is actually easier to do without the commandline.
- Download the installer here and run it.
