Javac is not recognized. Recently I started a fresh install of windows 10, however javac seemed to stop working. C: WINDOWS system32javac -version 'javac' is not recognized as an internal or external command, operable program or batch file. Please tell me if you have the solution.

When you install a program (here: javac.exe), you can start that program in two ways:
- Type the full path: 'C:Program FilesJava 1.X.Ybinjavac' MyStuff.java (note the quotation marks; they are needed because of the spaces in the path name)
- Change into the directory, then issue the command: cd 'C:Program FilesJava 1.X.Ybin', then javac MyStuff.java (only if the file is in the same directory)
The solution to this is setting the PATH variable. It holds a ; seperated list of folders, where your executable files live. Set it like this for one time change: set PATH='%PATH%;C:Program FilesJava 1.X.Ybin'. Now you can issue the command javac MyStuff.java in the folder with your source, or from any other folder, without typing the whole path every time.
See other post for setting this permanently. Hope you enjoy coding!

You will need to use the full path of javac or but the bin folder of your JDK in your environment path.
Cannot give any specific details without knowing your platform.

The javac executable is probably not in your PATH variable.
Try typing
c:full_path_to_javabinjavac whatever.class
assuming your using windows.If that works you need to add the java bin to your PATH
To add the java bin directory to your PATH do the following from a command prompt
That's assuming that you installed java on the c drive.
To make this permanent add the javabin path to

from @Zayik,
VS Code recognizes that OpenJDK is not downloaded and informs user to download it from
https://developers.redhat.com/products/openjdk/overview/
https://developers.redhat.com/products/openjdk/overview/
Upon doing so, the user is still unable to use javac to compile the code. They receive the error
'javac' is not recognized as an internal or external command, operable program or batch file.'
'javac' is not recognized as an internal or external command, operable program or batch file.'

This is very frustrating to new users, and those who are rusty towards knowing about pathing and environment variables. At this point, the user is still stuck despite following VS Code prompt.
Once the JDK is downloaded, VS Code should probably either auto include the path in its built in terminal, or prompt the user to locate the JDK to add the path. At the very least, it could send a reminder that the pathing needs to be updated in order to use it and direct them to a useful link.
This would make setting up VS Code dramatically quicker for those who are just learning coding in general. It would also add convenience for those who are already more adept at coding by giving them one less thing to worry about.
