序列化（ObjectOutputStream和ObjectInputStream）（切记：out是输出到本地中,in是输入到程序中）

注意：序列化自定义类必须实现一个接口Serializable，在c#中序列化自定义类是使用特性也就是[Serializable]

//要实现序列化的类

public class Student implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;//序列版本号
private String name;
private int age;
public Student(String name,int age){
this.name = name;
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}

//ObjectOutputStream

public class ObjectOutputStreamDemo {
/**
* 序列化步骤：
* 1、创建字节流
* 2、创建序列化流
* 3、序列化操作
* 4、关闭流
*/
//使用序列化前提：保证进行序列化的类要实现Serializable接口
public static void main(String[] args) {

Student stu = new Student("张三",23);
FileOutputStream fos = null;
ObjectOutputStream oos = null;
try {
//1、创建字节流
fos =new FileOutputStream("student.stu");
//2、创建序列化流
oos = new ObjectOutputStream(fos);
//序列化操作
oos.writeObject(stu);
System.out.println("序列化成功！");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally{
try {
//4、关闭流
oos.close();
fos.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

}

//ObjectInputStream

public class ObjectInputStreamDemo {
//反序列化
public static void main(String[] args) {

FileInputStream fis = null;
ObjectInputStream ois = null;
try {
fis = new FileInputStream("student.stu");
ois = new ObjectInputStream(fis);
Student student = (Student)ois.readObject();
System.out.println(student.getName()+"-"+student.getAge());
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally{
try {
ois.close();
fis.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}
