Well you're closing input in the finally block of the constructor, before you actually start using it. Move the closing part out of the constructor to somewhere it will be called when you're done, such as below the call to arrayListWithNumbers or a separate close method that you call from you main.

I think you are confusing finally with finalize() which you should not use for this purpose either.
