Thread: FocusListener

I am trying to create a FocusListener method that I where I can pass the method to be called. For example (and I know this doesnt work)

private void addFL(Component aptjf, Component met1, Component met2){
        aptjf.addFocusListener(new FocusListener(){
            public void focusGained(FocusEvent e){
                met1();
            }
 
            public void focusLost(FocusEvent e){
                met2();
            }
        });
    }

How would I pass met1 and met2 as methods to be run?

I am trying to do some form of field validation. Basically I have say 5 JTextFields on a form and when a user completes a field and it loses the focus I want it to validate the entry and if the entry is correct or incorrect indicate that with a visual indication (I used a plus and a cross icon to indicate this)

I was trying to simply this sort of thing:

aptjf.addFocusListener(new FocusListener(){
            public void focusGained(FocusEvent e){
                met1();
            }
 
            public void focusLost(FocusEvent e){
                met2();
            }
        });
 
aptjf2.addFocusListener(new FocusListener(){
            public void focusGained(FocusEvent e){
                met3();
            }
 
            public void focusLost(FocusEvent e){
                met4();
            }
        });
 
aptjf4.addFocusListener(new FocusListener(){
            public void focusGained(FocusEvent e){
                met5();
            }
 
            public void focusLost(FocusEvent e){
                met6();
            }
        });

to something a little cleaner liike

addMyFocusLister(NameOfTextField, MethodIfFocusGained, MethodIfFocusLost);

Or is this just not possible?
