如何將一個Java對象寫到文件裏

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.Serializable;

class Student implements Serializable {

  private static final long serialVersionUID = -6601903208557464574L;

  private String id;
  private String name;

  public Student() {
    super();
  }

  public Student(String id, String name) {
    super();
    this.id = id;
    this.name = name;
  }

  public String getId() {
    return id;
  }

  public void setId(String id) {
    this.id = id;
  }

  public String getName() {
    return name;
  }

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

}

public class SerializeToFileTest {

  public static void main(String[] args) throws IOException,
      ClassNotFoundException {
    Student o = new Student("1001", "張三");
    FileOutputStream os = new FileOutputStream("D:\\student.data");
    ObjectOutputStream oos = new ObjectOutputStream(os);
    oos.writeObject(o);
    oos.flush();
    oos.close();

    FileInputStream is = new FileInputStream("D:\\student.data");
    ObjectInputStream ois = new ObjectInputStream(is);
    Student deserialized = (Student) ois.readObject();
    ois.close();
    System.out.println("學號：" + deserialized.getId());
    System.out.println("姓名：" + deserialized.getName());
  }

}

1、序列化
2、ObjectInputStream ObjectOutStream**
