I am developing a simple image editor and need the user to be able to change the iconImage displayed in a JLabel. If I use setIcon to change the image, am I adding layer upon layer of iconImages on the JLabel (thus unnecessarily consuming memory) or does setIcon remove the previous icon (icon1) and add the new one (icon2)?

If I have to manage the removal process myself, how do I do so?

Imagine setIcon() method is any setXXX methods() in POJO. What happens if XXX is set? Replaced or new instance is created?

However keeping track of which JLabel's icon need changing is something you should consider.
