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)

Code :

---

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?

You can't pass methods (at least not yet). If you described what you're actually trying to accomplish, perhaps we could point you in a better direction.

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:

Code :

---

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

Code :

---

addMyFocusLister(NameOfTextField, MethodIfFocusGained, MethodIfFocusLost);

---

Or is this just not possible?
