Vector<String> strVector = new Vector<String>(Arrays.asList(strArray));

Breaking this down:

  • Arrays.asList(array) converts the array to a List (which implements Collection)

  • The Vector(Collection) constructor takes a Collection and instantiates a new Vector based off of it.

  • We pass the new List to the Vector constructor to get a new Vector from the array of Strings, then save the reference to this object in strVector.

Call the constructor of Vector that uses an existing collection (your array, in this case) to initialize itself:

String[] strings = { "Here", "Are", "Some", "Strings" };
Vector<String> vector = new Vector<String>(Arrays.asList(strings));
