实例化----serializable--也是种创建对象的方法

 

 

public  class  Serializable_ {

        public  static  void  main(String[] args)  throws  Exception {

             write( "D:/javac/10.txt" );       //序列化

            ObjectOutputStream oos =  new  ObjectOutputStream(

                          new  BufferedOutputStream(

                                      new  FileOutputStream(dest)

                                    )

                        );

            

            oos.writeObject(obj);

            

            oos.flush();

      }
