序列化和反序列化、 对象的序列化流
序列化和反序列化
图解:
对象的序列化流
ObjectOutputStream:对象的序列化
作用:
把对象以流的方式写入到文件中
构造方法:
ObjectOutputStream(OutputStream out)创建写人指定 ObjectOutputStream 的 ObjectOutputStream
参数:
OutputStream out:字节输出流
特有的成员方法:
void writerObject(Object o)将指定的对象写入 ObjectOutputStream
案例:
public class Student implements Serializable {
String name;
int age;
public Student(String name, int age) {
this.name = name;
this.age = age;
}
public Student() {
}
@Override
public String toString() {
return "Student{" +
"name='" + name + '\'' +
", 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;
}
}
创建学生类
public class Xujie {
public static void main(String[] args) throws IOException {
Student student = new Student("大傻",13);
ObjectOutputStream stream = new ObjectOutputStream(new FileOutputStream("aa.txt"));
stream.writeObject(student.toString());
stream.flush();
stream.close();
}
}
看运行结果:
