当我们查看产生的hello.txt的时候，看到的是乱码。因为是二进制文件。

虽然我们不能直接查看里面的内容，但是我们可以使用ObjectＩｎｐｕｔＳｔｒｅａｍ类查看：

public class ObjectInputStreamDemo{
 public static void main(String[] args) throws Exception{
 File file = new File("d:" + File.separator + "hello.txt");
 ObjectInputStream input = new ObjectInputStream(new FileInputStream(

 Object obj = input.readObject();
 input.close();
 System.out.println(obj);
 }
