The Blackberry JDE does not include java.util.ArrayList, even though it knows about java.util? What's up with that? Is there an equivalent class for BB? I don't want to use an array, really, because I have an unknown number of objects I'm dealing with. why does the Blackberry JDE leave so much out?
Well they are Java from a language standpoint. It just doesn't support all of the standard edition packages. It falls more inline with the microedition standards, but is way beyond J2ME from a package standpoint. They don't go around saying they're in compliance with J2SE 1.6, but it's still Java.
And of course it has arrays, unless you mean the class, Arrays. But, they have that too. It's located in package net.rim.device.api.util.
