Showing titles in ListView by selected date

[Kuba Parys]

Hello.
I'm trying to write a program, that display list of movies that are aviliable in selected date in DatePicker. I'm adding movie showing date by another DatePicker, and it's working well(when i choose showing day, it saves, so I can see it again when i want to edit details). But I have a problem displaying titles by selected date. I was trying to do it by adding

if(showingDate.getValue() == emissionDay.getValue())

before setting titles in list, but it didn't seem to work. (showingDate is choosen date, and emissionDay is saved date for movies).
Can you help me, how I have to write part of code that check, if choosen and saved date are the same and show me right titles in list?

I don't know what kind of data you're trying to compare with that code, but you should normally use the == operator only to compare primitive values. To compare two objects for equality you should use the equals() method. Like this:

if(showingDate.getValue().equals(emissionDay.getValue()))

Right, C++ habbit. But when I use equals(), i get NullPointerException..
