Checking for null pointers
Nov 7th, 2009, 10:32am  
I've got a pretty sizable array to sort through (say, [4000][4]), and the dataset it's built from occasionally has missing fields. When working with certain datasets, I'll hit a missing entry in the array, and get thrown a Null Pointer error.
Is there any way to check whether an array value is null before attempting to operate on it?

Yes.
Just do if (arr[i] != null)
