javac not working in windows command prompt
command-prompt, java, javac, windows
Solution
If you added it in the control panel while your command prompt was open, that won't affect your current command prompt. You'll need to exit and re-open or simply do:
set "path=%path%;c:\program files\java\jdk1.6.0_16\bin"
By way of checking, execute:
echo %path%
from your command prompt and let us know what it is.
Otherwise, make sure there is a javac in that directory by trying:
"c:\program files\java\jdk1.6.0_16\bin\javac.exe"
from the command prompt. You can also tell which executable (if any) is being used with the command:
for %i in (javac.exe) do @echo %~$PATH:i
This is a neat trick similar to the `which` and/or `whence` commands in some UNIX-type operating systems.
Problem
I'm trying to use `javac` with the windows command prompt, but it's not working. After adding the directory `"C:\Program Files\Java\jdk1.6.0_16\bin\"` to the end of the `PATH` environment variable, the `java` command works fine, but using `javac` gives me the following error: 'javac' is not recognized as an internal or external command, operable program or batch file.
