大侠指点一下怎么clone对象
我用下面的方法clone一个Object[]对象,怎么不行,请大侠赐教,怎么做,最好给点具体的代码,谢谢了。.分没有了 
 public   class   ClassroomContainer   implements   IClassroomContainer,   Cloneable   {     
 	public   Object   clone()   { 
 		try   { 
 			return   super.clone(); 
 		}   catch   (CloneNotSupportedException   e)   { 
 			throw   new   InternalError(); 
 		}   
 	}	   
 for   (int   b   =   0;   b    <   buildingOfClassrooms.size();   b++)   { 
             Object[]   classroom   =   (Object[])   buildingOfClassrooms.get(b); 
             Object[]   newClassroom   =   (Object[])   classroom.clone(); 
 }   
 .... 
 }
------解决方案--------------------Object[] 这是复制一个对象数组啊,你不能单独的复制吗? 
------解决方案--------------------这个问题值得思考,以前我也没碰到这样的问题,也希望高手解答下
------解决方案--------------------public Object objectClone() { 
         Object clone = null; 
         ByteArrayOutputStream output = new ByteArrayOutputStream(200); 
         try { 
             ObjectOutput writer = new ObjectOutputStream(output); 
             writer.writeObject(this); 
             writer.close(); 
         } catch (
IOException e) {              
System.err.println( "Class not found:  " + e); 
         }   
         InputStream input = new ByteArrayInputStream(output.toByteArray()); 
         try { 
             ObjectInput reader = new ObjectInputStream(input); 
             clone = (Object) reader.readObject(); 
         } catch (IOException e) { 
             System.err.println(e.toString()); 
         } catch (
ClassNotFoundException e) { 
             System.err.println( "Class not found:  " + e); 
         } 
         return clone; 
     }
------解决方案--------------------楼上说的对,注意复制的对象,还有它的引用对象必须序列化。否则报异常。
