For example, s are exceptions that occur when you try to use a reference that points to no location in memory (null) as though it were referencing an object.Calling a method on a null reference or trying to access a field of a null reference will trigger a because there is no code to execute in the location that the reference is pointing.But you can be sure that the second line (the first "at" line) will tell you where the NPE was thrown This is the hard part.
