How to check for null int/null Date

Question

Heres the situation, there is an interface accepting an int value and a time/date that are not required(and are not set to anything automatically, i have no control over that part unfortunately), but I need to set up some sort of null/has value type of check to execute the setter when it does have a value, and ignore it when it doesnt. I am currently getting null pointers. here is my current set up:
//throws null pointer as set up below, I am assuming I might want to eliminate the "getDate" off of the end and that might clear it up.
if(data.getDate().getTime() != null)
          tempData.setDate(data.getDate().getTime());
//Not sure on this one yet, the value doesn't get set to anything so I am assuming it automatically gets assigned something like -1.
if(data.getId() >= 0){
          tempData.setId(data.getId());
          }

I know data isnt null because it goes through a bunch of other tempData.set(data.get) items prior to hitting a snag on the above date I mentioned, when there is no value input for the date. and that particular null check I do there, does not work because it throws a null pointer in the if statement itself.
i.e. it traces the null pointer to
(if data.getDate().getTime != null) //this is the line the null pointer traces to.{color:#3D2B1F}if data is not null, then it must be the case that data.getDate() is null. Now that's what I call logic. W00t!{color}
