There is no way to increase the size of an array. You have to create a
new array however big you need it and then copy the old array into it.

If this is really what you want to do, of course.

If you you are regularly doing this on large arrays you will end up with
a very poorly performing implementation. You should look at using a
LinkedList or ArrayList. These are implementations of the List
interface of the collections API. This is really what you probably
want.

Hmm. Maybe in how you would implement one. Take a look at Stack too.
