Array dimension missing

[Stephanie Dears]

I have a line in my code:

int array = new int[] array;

the error is array dimention missing

What does this mean?

To declare an array you need something along the lines of

int[] anIntArray = new int[10];

This declares 'anIntArray' to be an array of length 10.

It's reading from a .txt file.

You can declare an array of unknown size like this:

int[] array;

but there's no array object there. You can't use "new" to actually create the object until you actually know the size.

If you don't know the size -- that's what we're talking about here, right? -- then don't use an array: use one of the Collections classes in java.util. For example, java.util.ArrayList, which is rather like an array, but it grows automatically as you add items to it.
