event handling with button
Hi All,
I am trying to write an event handling on my button, but i seem dont know where to start from. My code are below:
import java.net.*;
import java.io.*;
public class ReadWrite
{
public static void main(String[] args) throws Exception {
URL myLocalhost = new URL("http://localhost/Write.pl");
URLConnection myURL = myLocalhost.openConnection();
BufferedReader myBR = new BufferedReader(
new InputStreamReader(
myURL.getInputStream()));
String inputLine;
while ((inputLine = myBR.readLine()) != null)
System.out.println(inputLine);
myBR.close();
}
}
--
I want to write a code with a button to run the above code.
Could you please advise?
Thank for any consideration you may give me.

setLocation(400,300);
setSize(200,100);
setDefaultCloseOperation(EXIT_ON_CLOSE);
JPanel panel = new JPanel();
JButton btn = new JButton("Read/Write");
btn.addActionListener(this);
panel.add(btn);
getContentPane().add(panel);
}
public void actionPerformed(ActionEvent ae)
{
BufferedReader myBR = null;
try
{
myBR = new BufferedReader(new FileReader("Test.txt"));
String inputLine;
while ((inputLine = myBR.readLine()) != null)
{
System.out.println(inputLine);
}
myBR.close();
}
catch(Exception e){e.printStackTrace();}
}
public static void main(String args[]){new Testing().setVisible(true);}
