can anyone help me out by letting me out that how ethereal actually captures tha packets on ethernet ports....
It uses a library called libpcap on various UN*Xes, which uses the various native mechanisms on those UN*Xes, and a library called WinPcap on Windows, which is a driver to provide a mechanism for WinPcap to use plus a port of libpcap to use that mechanism. 


how it can be done through JAVA..


Try jpcap:

	http://sourceforge.net/projects/jpcap
which is a set of Java classes to use libpcap (and perhaps WinPcap; they speak of it supporting Windows).
Is there any option for doing it using Visual basic 

Here's the item about that in the WinPcap FAQ:
