Java SE (Java Platform, Standard Edition)

Hi there,

I have a Java application that reads some information from a file on the file system.

It is really basic, I have some info on the application that the user enter and then the user hits a button. From there the application calls a new class that does some IO from a file and then returns.

However, the actionPerformed method I am using does not seem to allow IOExceptions here is a sample:

import javax.swing.*;
import java.awt.event.*;
import java.io.*;

public class mainWindow implements ActionListener
{
   JButton go = new JButton("Go");

  public void actionPerformed(ActionEvent e)
  {
        //This loads my IO class
        doIO getInfo = new doIO( );

   public mainWindow
   {
       //does all the mainWindow things
       go.addActionListener(this);
   }
}

That is basically my window that calls the other class, obviously there is a lot of fundametals missing but the main problem is in the actionPerformed method.
When I try and do that I get the error "Unhandled Exception type IOException"

This is where the problem gets a little wierd, my class doIO looks something like this:

import java.io.*;

public class doIO
{
   public doIO ( ) throws IOExcpetion
   {
      //All my Io Stuff
   }
{

Since the method actionPerformed in part of the Interface ActionListener I cannot use the "throws IOException" on that method.


Any suggestions?
