* ClassPath can be present at drive/folder/subfolder ..
* Java compiler or runtime environment won’t be able to find the classes unless they are somewhere in the class path
* Multiple entries in the class path are separated by a semicolon on Windows (;) and by a colon on UNIX (:)
* To limit the search to particular locations, Operating System Environment variable CLASSPATH is being used
