    Pass the List as a parameter to the constructor of a new ArrayList.

    List objectList = new ArrayList(stringList);



    Any Collection can be passed as an argument to the constructor as long as its type extends the type of the ArrayList, as String extends Object.  The constructor takes a Collection, but List is a subinterface of Collection, so you can just use the List.
