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));

     }

 }
