javac not recognized

Question

What can I do when I keep receiving the error

\'javac\' is not recognized as an internal or external command, operable program or batch file

Answer 1

This just means that javac isn't in your PATH variable.

On Windows, you just have to add the folder that contains javac.exe to the PATH environment variable (Win+Pause/Break).

On Linux/Mac/Unix, just append that directory to $PATH in .bashrc or similar.
