发帖数: 220 | 1 First create: Activity[] temp = new Activity[100];
after finishing using that temp array, I want create another temp array
for the following purpose.
while(temp.length>0)
that is I want repeatedly to check above condition in while loop, while
each time the contents in temp array are different.
Thanks | c*****t

Maybe ArrayList will fit your usage better.

look out for null pointer.

发帖数: 2416 | 5 I know it's probably just different terminology, but I just could't help --
you can _reassign_ an array, but you can't _redefine_ it, not with the same
scope.
while
