How to read URL by button action event

Question

Hi,
Can some one please show me how to add a ...... I call it URL reader to the action of a button of another class?
Lets say I have a url reader class and the following code
public void uRLReader() throws Exception {
         // URL concatenation
         String url1 = "http://";
         String url2 = "";
         String url3 = ".google.com";
         URL google = new URL(url1+url2+url3);
         BufferedReader in = new BufferedReader(
                        new InputStreamReader(
                        google.openStream()));
         String inputLine;
         while ((inputLine = in.readLine()) != null)
             System.out.println(inputLine);
         in.close();
        }Now I also got another class in the same package "class2", it has a button. Similarly, another class which has a JTextField. Now when some one writes 1 and hit the button I want "1" to get inserted into url in "url2" position. In other words any thing that is entered in the JTextField should be inserted into "url2" position.
I am not very much familiar with java so this is all I could write. I used a string concatenation to break the url. Can some please show me how do I add this to the button of another class and the button to JTextFiled of another class?
Thank you

First of all, change your method so that url2 is an argument of the method:
public void uRLReader(String url2) throws Exception {and remove the declaration of url2 from the body of the method.
Then, write and ActionListener class (it could be an anonymous inner class) to read the textfield you want, then invoke uRLReader, passing that text as an argument.
That's basically it.
