Not unless you defined a command named make--B-*.c

Typing M-x "javac nameofmyfile" RET may work only if you defined a
command named \"javac\ nameofmyfile\".

(defun \"javac\ nameofmyfile\" ()
  (interactive)
  (do-something))

And then, yes, you may type M-x "javac nameofmyfile" RET



Perhaps you wanted to type:

     M-x compile RET C-a C-k javac nameofmyfile RET

but that's something entirely different.

Right.

You should get the same path with:

           M-x compile RET C-a C-k echo "$PATH" RET
than with:
           M-! echo "$PATH" RET
