There are two ways to set java path

javac is not recognized as internal or external command, operable program or batch file.

3. Write in cmd : set path=C:\Program Files\Java\jdk1.8.0_121\bin
4. Write in cmd : javac

You can check that path is set if not error has been raised.

It is important to note that these changes are only temporary from programs launched from this cmd.

NOTE: You might have to run the command line as admin

B. Permanent

1. Righ-click on "My computer" and click on properties
2. Click on "Advanced system settings"
3. Click on "Environment variables"
4. Click on new tab of user variable
5. Write path in variable name
6. Copy the path of bin folder
7. Paste the path of the bin folder in the variable value
8. Click OK

The path is now set permanently.
