I've written many java apps; however, I have never created anything that communicated with the Internet, or more specifically, web pages. How exactly would you go about doing this.. For instance, say I wanted to write a program that would log me in Daniweb, and send messages or posts to all of its members..
Or, how would I write a program that would receive input from the user in the form of a user name, and then look up the username on a high scores webpage. The program would output the user's score, and subscore..
Am I making any sense at all? How difficult would it be to write something like this?
