Question about buttons in SWT

[instop]

Hi.
I have a problem. I've created SWT button, and now i'm trying to understand how to change variable x by pressing on it.
My code is:

public class Main{
     public static void main(String[] args) {
    	int x;

       Display display = new Display();
       Shell shell = new Shell(display);

       Button button = new Button(shell, SWT.NONE);
       button.addSelectionListener(new SelectionAdapter() {
       	public void widgetSelected(SelectionEvent e) {
               x = 1;
               System.out.println(x);
       	}
       });
       button.setBounds(69, 42, 75, 25);
       button.setText("123");
       shell.open();
       while (!shell.isDisposed()) {
          if (!display.readAndDispatch()) display.sleep();
       }
    }
}

But Eclipse says that x must be made final and as i make it final it says x can't be changed. How do i make button change x? Help me please.

Move it outside of the method and make it static.
