Description: In this we create a framework in which a student (a client)
can use an applet or application to displays her/his marks (for multiple courses). This
applet is automatically updated (using callbacks) when ever there is a change in students
marks from the server. Each student has its ID and password to login to the system.
Administrator can also login but it has more privilege then the student. Administrator can
add, selete and modify student information such as course he/she is registered, marks for
these courses and password etc. Persistence of the object is using file. If you want to
Shut down the server then everything is saved into the file.
