Returning custom objects from an ArrayList

[shredder249]

Hi,

I have one class called Track and another class called TrackList. TrackList is an ArrayList made up of Track objects. I can add Track objects to a TrackList but I cannot retrieve them as actual Track objects from the ArrayList, I can only retrieve them as generic objects. This means that I cannot use any methods from the Track class on them.

How can I get Tracks out of a TrackList as actual Track objects?

Cheers

Are you using generics so that you can retrieve Track objects from your TrackList(s) without an explicit cast? As in:

Track aTrack= new Track( ... );
List<Track> trackList= new ArrayList<Track>();
 
list.add(aTrack);
 
aTrack= list.get(0);
 

kind regards,

Jos

Ah I wasn't, I was using:

ArrayList TrackList = new ArrayList();

But now I've added the <Track> bits it works, many thanks!
