If you get the error javac is not recognized as an internal or external command, here’s the fix.
1. Step Enter SystemPropertiesAdvanced.exe into the search bar:
2. Step Click on the button Environment Variables…
3. Step The fieldset System variables has an item called Path, double-click on it.
4. Step Go to the very beginning of the line and add the path to your javac file e.g.
Add the ; to separate the path from the other system paths.
5. Step Keep in mind you need to replace that path with your own path (simply check C:\Program Files\Java). There is a newer version of the JDK available by now. The javac file should still be in the bin folder nonetheless
After adding the path to the javac file the error ‘javac is not recognized as an internal or external command’ should no longer appear. If you still get the error, first try a reboot.
Setting PATH via CMD
If it doesn’t work, enter this into a command prompt and try again
set PATH=C:\Program Files\Java\jdk1.6.0_18\bin;%PATH%
This will add the path to your current %PATH% variable (basically the same as above).
