序列化保存到问

序列化就是在类中实现序列化接口，序列化之后才可以保存到文件，或者传输。



import java.io.Serializable;

public class Person implements Serializable{

private String name;
private String sex;

public Person(String name,String sex){
this.name=name;
this.sex=sex;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getSex() {
return sex;
}

public void setSex(String sex) {
this.sex = sex;
}
}

//out 和 in相对于内存而言

=====================================================
public class TestDemo {

public static void main(String[] args) {
//创建一个对象
Person people = new Person("张三","男");
try {
//实例化ObjectOutputStream对象
ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("C:\\person.txt"));
//将对象写入文件
oos.writeObject(people);
oos.flush();
oos.close();

//实例化ObjectInputStream对象
ObjectInputStream ois=new ObjectInputStream(new FileInputStream("C:\\person.txt"));

try {
//读取对象people,反序列化
Person p = (Person)ois.readObject();
System.out.println("姓名："+p.getName());
System.out.println("性别："+p.getSex());
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}


} catch (FileNotFoundException e) {

e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}
