CodeCombat now offers a beta version of Java for classrooms. This means you can introduce your students to one of the most popular programming languages in the world.
Please note that since the Java version is still in beta, you may encounter some bugs while using it. If you do stumble across bugs you can let us know by sending an email to support@codecombat.com.
If you are interested in trying Java with your classroom send us a message and we can get that activated for you.
