Hi, I have a button declared at the class level i instantiate the button in the constructor and add an actionListener object to the same. while moving to the next screen if i set the button to null would the button be eligible for garbage collection or do i explicitly need to remove the actionListener object as well? Thank You, Phani.
You don't have to remove the actionlistener, for two reasons...
ActionListeners don't (normally) have a reference to the components they are attached to
Even if the ActionListener did have a reference to the button, as long as there wasn't another reference to the ActionListener, they would still be garbage collected. The GC is able to figure out circular dependencies.
