数组对象Vector用法

 import java.util.Vector;

 public class VectorTesting {
     public static void main(String[] args) {
         Vector<Object> _vector=new Vector<Object>();
         Integer intObj=new Integer(1);
         _vector.addElement(intObj);
         String strObj="1";
         _vector.addElement(strObj);
         Boolean boolObj=false;
         _vector.addElement(boolObj);
         System.out.println(_vector.size());

         Boolean newObj=false;
         _vector.set(0,newObj);
         _vector.remove(newObj);
         System.out.println(_vector.get(0));
     }
 }
