How do I clone a generic List in Java?

public Object clone()

ArrayList newArrayList = (ArrayList) oldArrayList.clone();

List<String> strs;
...
List<String> newStrs = new ArrayList<String>(strs);

//assume oldList exists and has data in it.
List<String> newList = new ArrayList<String>();
Collections.copy(newList, oldList);

ArrayList(String) copy = new ArrayList(String)();
copy.addAll(original);

ArrayList<String> orig = new ArrayList&<String>();
ArrayList<String> copy = (ArrayList<String>) orig.clone()

ArrayList first = new ArrayList ();
ArrayList copy = (ArrayList) first.clone ();
