T[]toArray(final T... items)

Create a type-safe generic array.

The Java language does not allow an array to be created from a generic type:

 public static <T> T[] createAnArray(int size) { return new T[size]; // compiler error here } public static <T> T[] createAnArray(int size) { return (T[])new Object[size]; // ClassCastException at runtime }

Therefore new arrays of generic types can be created with this method.
