I want to create one ticker just like Stock exchange sites are having some described scripts/stocks' will be added to the ticker and it keeps rolling, just like marque in HTML..
I want to make an application which is having the ticker identical to Stock market websites... what is the logic, or/and way to perform the coding for that?
Any specified website? Do you mean you want the user to be able to select where their data comes from? Sounds very difficult. It is easy enough to connect to a URL and read whatever is there (see java.net.URL), but without an API defining the content you are going to find it hard to do much with the data (and remember that you are probably going to need the permission of the site owner to use their data).
