对象序列化

保存对象

如果需要将自己定义的类的对象使用文件保存->序列化
那么这个类必须实现Serializable接口
FileOutputStream fos = null;
ObjectOutputStream oos = null;
try{
fos = new FileOutputStream(des);
oos = new ObjectOutputStream(fos);
Person p = new Person(18,"jack");
oos.writeObject(p);
}

读取对象

FileInputStream fis = null;
ObjectInputStream ois = null;
try{
fis = new FileInputStream(src);
ois = new ObjectInputStream(fis);
Person p = (Person) ois.readObject();
System.out.println(p.toString());
}
