/**
* 数组遍历器
*
* <pre>
*    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();
*
