ActionListener in Java

Question

Hi
I have a performance question on ActionListener
One way to add an actionListener to a button is to do it this way
JButton[] button = new JButton[10];
for(int i=0;i<<10;i++)
     button[i] = new JButton();
     button.addActionListener(new ButtonActionListener());
class ButtonActionListener implements ActionListener
     public void actionPerformed(ActionEvent event)
//some code
is the example above more memory consuming then
this version
ButtonActionListener actionButtonClass = new ButtonActionListener()
JButton[] button = new JButton[10];
for(int i=0;i<<10;i++)
     button[i] = new JButton();
     button.addActionListener(actionButtonClass);
class ButtonActionListener implements ActionListener
     public void actionPerformed(ActionEvent event)
//some code

Hi there
thanx for your answears but...
In the case above all those buttons are activating different tools so my actionlistener looks like this
class BALhistoryBP implements ActionListener
     public void actionPerformed(ActionEvent event)
          hideWindow(currentWindow);
          if(event.getActionCommand().equals("moveexam"))
               currentWindow = 9;
          else if(event.getActionCommand().equals("newexam"))
               currentWindow = 7;
          else if(event.getActionCommand().equals("import"))
               currentWindow = 12;
          else if(event.getActionCommand().equals("export"))
               currentWindow = 13;
          showWindow(currentWindow);
          back(currentWindow);
}Is it still a good way to create an object of this class and provide it to each button
as in example 2 posted above?
Or should there be a new listener for each button (don't seem right)

One more question
I have detected that a mouse listener seems slower then an actionlistener is this true?
(Or is it my imagination)
