Adding to the comparison topic, when you have to compare two objects and any of them could be null, you can leverage the util method Objects#equals(Object a, Object b). It is available since Java 7 and its implementation is very simple:
Objects#equals(Object a, Object b)
return (a == b) || (a != null && a.equals(b));
Indeed, the Objects.equals() method is really usefull and saved many apps, including mine, from crashes :D
