Arrays

-----------------------------------

Is there any way to create an array with a long variable as the number of positions?

If you don't know what I mean by that (Since I'm not great at explanations.):

I have this:
 
boolean primes[] = new boolean [num + 1];

But I wanted to have num be a long type variable rather than int. Why doesn't it let me do that? And is there any way to get around this?

No, you cannot.  This is a limitation imposed by the language that you'll have to deal with.  Is there any particular reason you need an array that big?

The size of the array is based on the user's input, so I was just trying to see if I could make it a larger number if need be. But it's not crucial. Thanks for the help.
