I am aware that the correct syntax for creating new collection
is as follows:
ArrayList<type> list = new ArrayList<type>();

  This is an expression statement. There is not a unique
  "correct syntax for creating new collection [objects]", while
  usually an invocation of a factory method or an instance
  creation expression ist involved.

Could someone show me the correct syntax (if any) if one gets
the collection from a known casted object as below. ie., where
should I put <type> on the right side?
ArrayList<type> list = ((SomeClass)someClassObject).getSomeCollection();

  There is no need to do so, though it might be possible in some
  cases. This depends on how ?getSomeCollection? is declared
  (see its documentation). If it takes a type argument at all,
  it would look like:

object.<type>method();

  This does not necessarily have to be the same type as in
  ?ArraysList<type>?. And this is not ?collection syntax?, but
  method invocation syntax.
