Debugger is free, but it may not support those languages. Or at least, it might not support them out of the box; they’re not listed as languages with preconfigured debuggers.
You’d have to check with the package author, but presumably if there is a DAP enabled client for those languages it would work with the package.
Have you guys been able to find a DAP for java debugging. It will be really nice if someone can explain me how to setup the debugger for java.
