dowload a file from website ?

[friend.05]

Hi,


I am working one network security project. For that I need
vulnerabilities database fron NIST website. On NIST website they
provide vulnerabilities databse.


I want to develop a java program, so when user clicks on listener
download vulnerabilities database, it should dowload the database from
website.

And then I want to extract some data from it , and write onto database

can anyone suggest how can I do this?
