Java将对象写入文件读出_序列化与反序列化的实例

File aFile=new File("e://c.txt");    Stu a=new Stu(1, "aa", "1");    FileOutputStream fileOutputStream=null;    try {      fileOutputStream = new FileOutputStream(aFile);      ObjectOutputStream objectOutputStream=new ObjectOutputStream(fileOutputStream);      objectOutputStream.writeObject(a);      objectOutputStream.flush();      objectOutputStream.close();    } catch (FileNotFoundException e) {      // TODO Auto-generated catch block      e.printStackTrace();    } catch (IOException e) {      // TODO Auto-generated catch block      e.printStackTrace();    }finally {      if(fileOutputStream!=null)      {        try {          fileOutputStream.close();        } catch (IOException e) {          // TODO Auto-generated catch block          e.printStackTrace();        }            }    }

FileInputStream fileInputStream=new FileInputStream(aFile);ObjectInputStream objectInputStream=new ObjectInputStream(fileInputStream);Stu s=(Stu)objectInputStream.readObject();System.out.println(s);
