例子： import java.util.Vector; public class DIC { public void addObjects (Object[] o) { // if length > 10, Vector needs to eXPand for (int i = 0; i< o.length;i++) { v.add(o); // capacity before it can add more elements. } } public Vector v = new Vector(); // no initialCapacity. }
更正： 自己设定初始大小。 public Vector v = new Vector(20); public Hashtable hash = new Hashtable(10);
