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

You have to do like this

set path=%path%;C:\Program Files\Java\jdk-11.0.1\bin\

see no space arround =

If you want to make this permanent

Open run dialog box and enter sysdm.cpl

go to advance tab -> envirnment variable
and then edit the path in system variable

If you have windows 8 or later then

• click on new and paste C:\Program Files\Java\jdk-11.0.1\bin\

Or if you have windows 7 then

• paste ;C:\Program Files\Java\jdk-11.0.1\bin\

CMD/PowerShell: 'javac' is not recognized as an internal or external command, operable program or batch file

You only need to add the Java bin location to the global PATH variable. So, you will be able to execute Java commands anywhere on the computer.

javac not working in windows command prompt

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.

Java path problems, 'java' is not recognized as an internal or external command, operable program or batch file. (javac too)

There is a typo in the path. Correct me if I'm wrong but on Windows

JAVA_HOME should be C:\Program Files\Java\jdk-15.0.2 and PATH should start with %JAVA_HOME%\bin;.

Next time, just copy-paste the path from Windows Explorer to avoid this.
