Passing List<String> to String... parameter

Question

I'm struggling to pass a List of Strings into a method requiring the parameter "String...".

Can anybody help me out?

// How to put names into dummyMethod?
List<String> names = getNames();

---

 public void dummyMethod(String... parameter) {
    mInnerList.addAll(Arrays.asList(parameter));
}

Answer 1

You'll have to convert the List<String> to a String array in order to use it in the 'varargs' parameter of dummyMethod. You can use toArray with an extra array as parameter. Otherwise, the method returns an Object[] and it won't compile:

List<String> names = getNames();
dummyMethod(names.toArray(new String[names.size()]));

Answer 2

You can do the following :

dummyMethod(names.toArray(new String[names.size()]) 

this will convert the list to array
