  • Use a List, such as an ArrayList. It's dynamically growable, unlike arrays (see: Effective Java 2nd Edition, Item 25: Prefer lists to arrays).
  • This method returns an array of type T containing all the elements of the List in the sequence returned by List’s iterator. If the specified array is large enough to fit all the List elements, it is returned, otherwise a new array is created with the type T and size of the List and returned.
  • The java.util.Arrays.toString(int[]) method returns a string representation of the contents of the specified int array. The string representation consists of a list of the array's elements, enclosed in square brackets ("[]") .
