I was wondering if there was any way that i could compare and index of an arrayList and a array. I tried using the > operator and that didn't work.
I have tried something like this
if(ArrayVar[i] > arrayList.get(i) )
and i get errors.

1you can't compare an Object with an Integer; if you know that the Object is actually an Integer, then you will need to typecast it ((Integer) myObj) then make the comparison.Lie Ryan– Lie Ryan2010-09-19 20:44:46 +00:00Commented Sep 19, 2010 at 20:44

You say that the array is of type Object and the arrayList is an Integer type. You are comparing apples and oranges.
Assuming the array acutally holds Integers as their Objects, you can cast that to an Integer and do the comparison then.
If the array doesn't have Integers (or any kind of number) how do you expect to compare them?
