Source: GitHub README

Web-based IDE for Java-Programming (Java 8), which is fully functional to Java except UIs (obviously), writing files to disk, accessing the internet and a few others. The restrictions are needed for security reasons and are provided by Java’s security manager.
Each user can create private projects and teachers can convert their projects into assignments, which are then editable by the pupils of the selected course.
Pupils directly see coding-assignments when logging in and they can code, compile, run and test their assignments completely online without the need of an offline installation of the JRE or any other software.
JUnit for automatic testing of the assignment - the newest test-result (percent of how many JUnit-Tests passed successfully) of pupils is directly visible to the teacher.
Teachers can open pupils solutions with a single click and show/compare them at the beamer in the classroom without the necessity of sending directories or files.
After a configurable start-date, pupils can see the solution of the teacher and compare it with their own solution.
Pupils can only open their own project or assignment - no possibility to open the assignment-solution of your best buddy. That’s first because of privacy-reasons and second to minimize copying from others.
Schoco is available in english and german language. Other languages can be added easily, see here.
