Usage

From source file:MainClass.java

public static void main(String args[]) {

    // initial size is 3, increment is 2
    Vector<Integer> v = new Vector<Integer>(3, 2);

    System.out.println("Initial size: " + v.size());
    System.out.println("Initial capacity: " + v.capacity());

    v.addElement(1);//from w  w  w.  j  a v a 2s.  c  om
    v.addElement(2);

    System.out.println("First element: " + v.firstElement());
    System.out.println("Last element: " + v.lastElement());

    if (v.contains(3))
        System.out.println("Vector contains 3.");
