when trying adopt style of implementing listener using anonymous or nested class in order hide notification methods other uses listening (i.e. don't want able call actionperformed). example java action listener: implements vs anonymous class : public myclass() { mybutton.addactionlistener(new actionlistener(){ public void actionperformed(actionevent e) { //dosomething } }); } the question if theres elegant way remove listener again using idiom? figured out instantiation of actionlistener not produce equal objects every time collection.remove() won't remove added object. in order considered equal listeners should have same outer this. implement equals need hold of outer other object. go (which find little bit clumpsy): interface mylistener { object getouter(); } abstract class myactionlistener extends actionlistener implement mylistener { } public myclass() { mybutton.addactionlistener(new actionlistener() { ...
