Online compilers

• Online GDB
  • Includes debugging support, which is very useful.
  • Also supports a host of other languages, including C++, Python, and JavaScript.
• JDoodle

Sample problems we use for training

• Some little projects that Mr. Healy has been writing up
  • Note: for programming the robots in FRC, we frequently only use a limited subset of the functionality provided by the Java language. As a result, the "boot camp" material covered in the above problems is meant to focus on some core pieces of the Java language that are useful for that purpose, but are nowhere near a complete "tour of the language", or even of what we need to work on the robot. If you're interested in going further, Mr. Healy will be very happy to help you to do so.
