Get sprcific data from a look up website

I'm totally new to this section of networking with java. What I'm trying to do is that, I want the user to add machine type and serial and when he press a button, this will extract the machine expiration date, model and country from a website and then put this data in a txt file automatically. I'd like as well that the browser to be hidden but don't know how to do it. I will really appreciate your help. As well I would prefer to use JTextArea with a vertically only scroll pane to allow the user adding more than one machine (let's say 50 machines) at once , but as well, I don't know how to make the program read the type and serial from this JTextArea separatly Here is my current code
