/**
* 数组 遍历器
*
* 


  *    Object[] objects=new Object[5];
  *    objects[0]="string";
  *    objects[1]=new Integer(1);
  *    objects[2]=new Double(1d);
  *    obejcts[3]=new Date();
  *    objects[4]=new Boolean(false);
  *    正常访问：
  *      String str=(String)objects[0];
  *      Integer i=(Integer)objects[1];
  *      Double d=(Double)objects[2];
  *      Date date=(Date)objects[3];
  *      Boolean bool=(Boolean)objects[4];
  *    Example:
  *      ObjectQueue queue=new ObjectQueue(objects);
  *      String str=queue.getString();
  *      Integer i=queue.getInteger();
  *      Double d=queue.getDouble();
  *      Date date=queue.getDate();
  *      Boolean bool=queue.getBoolean();
  *
