Solution 1

When you declare an array, the length has to be known, as the array is considered as a contiguous block of memory, which has to be allocated together.
If you want to use an array where you do not know the length until you have filled it, consider using a List<T> instead and use the Add method to just keep adding elements - you can use the ToArray method later to get the array content if you need it.

Sorry - I don't know enough about Java to comment, but I would imagine it is much the same.
