best way to convert an array of strings to a vecto

问题:

As the title suggests, what is the best method for converting an array of strings to a vector?

Thanks

回答1:

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));

回答2:

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.

new Vector(Arrays.asList(array))
