Students are often asked not to use an IDE (I like Visual Studio Java) for their Java projects. Instead they need to use BBEdit without an IDE. BBEdit does not appear to natively support facilitated compile/execute but it does run AppleScrips that can speed things a bit.
The davalign.com site has some scripts written for TextWranger. If you rename them to BBEdit they work well.
Reproducing them here in case that site vanishes. I didn't see much like this. Note if you open and save in macOS Script Editor they will be compiled. I like that the first action is to save the document, it's easy to forget to save before a compile.
