Passing vector into class/methods

Question

I am new to Vectors check this simple code out. I am trying to pass a vector onto another class then add an integer element to it. I see that its looking for an identifier but i dont unerstand how the code is for an identifier for a vector.
ERRORS: .\Remove.java:4: <identifier> expected
     public static void AddIntegers(varray);
^
.\Remove.java:4: ')' expected
     public static void AddIntegers(varray);
^
.\Remove.java:4: cannot resolve symbol
symbol : class varray
location: class Remove
     public static void AddIntegers(varray);
^
C:\Computer Work\Lab4\RemoveTest.java:11: cannot resolve symbol
symbol : method varray ()
location: class RemoveTest
          rm.AddIntegers(varray());
^
.\Remove.java:4: missing method body, or declare abstract
     public static void AddIntegers(varray);
^
.\Remove.java:6: cannot resolve symbol
symbol : variable varray
location: class Remove
          varray.AddElement(new Integer(13));

I think the question whether you should use Vector over arrays, but rather should you use Lists over arrays. Vectors are kind of deprecated. You should be using the Collections Framework as a whole, and that means that ordered items are in java.uti.Lists, where are a kind of java.util.Collection, and a Vector is just a particular kind of List, and not necessarily even the best kind -- an ArrayList or LinkedList is often better.
The advantage of arrays over Lists is that they can hold primitive types trivially. You can only hold objects in Lists, so you can put primitive class wrapper objects in Lists, but that has its disadvantages. Apparently in JDK 1.5 there's some syntactic sugar to make this easier, but there are still other disadvantages.
The advantages of Lists over arrays are like what you mentioned -- things like resizings are automatic, there are lots of convenience methods, etc. The Collections Framework provides an abstraction of, well, collections, which is a good thing over futzing with details like with arrays, frequently.
