I have heard about a few classes like HTMLAnchor,HTML Button,HTMLText field........et c.
However, what is the use of those classes? Some say they correspond to HTML controls on the page.
But how do I use it....and ain't these HTML controls independent...I mean they really don't have any OOP relation.Do they?

Zaid181294 replied to What is the difference between getPort() and getLocalPort() of the Socket class?in JavaBut isn't a Socket like an end point between two communicating entities.for instance,
server--------------------|socket|-----------------client
So the question arises that how can we have two end-points in a connection.( I seriously can't grab this one!!!)Leave a comment:

Some may say thatreturns the "Local Port" andCode:getLocalPort()
returns the "remote Port" but what i find interesting yet ironically confusing is that how can be there two ports associated with the same Socket?Code:getPort()
