You need to install two pieces of software: The Java Development Kit (JDK) and the Eclipse IDE (Integrated Development Environment).
1) The Java Development Kit (JDK).
The Olin labs have installed JDK 10. If you want your computer to match exactly, you can download JDK 10 here:
However, technology moves quickly, and there's already a newer version, JDK 11, available, which should also work for this class.
2) Eclipse
The Olin labs have Eclipse "Photon" installed (available here), but once again there's already a newer version (Eclipse 2018-09) that you could install.
