I have this piece of code:

EventSnapshot snapshotEvent = new EventSnapshot();

EventSnapshot currentEvent = new EventSnapshot();

do
{
   ...              
currentEvent.setContent(in_stats); 
   ...              
if(!snapshotEvent.equals(currentEvent))
    snapshotEvent.setContent(in_stats);
}
while(true);

At the first cycle I get a NullPointerException because obviously the object snapshotEvent is empty. At the second cycle this doesn't happen.how can avoid this problem?
