java command not found windows

1Have you checked your environment variables for Windows? When you installed the 
2JDK/JRE the directory should have been added to the PATH variable. The directory
3added needs to contain the java.exe executable. It should be located in 
4C:\Program Files\Java or something like that if you installed it using the 
5default settings. Once you find that directory find the bin directory inside it.

13JDK /bin directory is there, if it is not then add it.
