serial.java

用java编写的一些初级代码

import java.io.*;
public class serial
{
    public static void main(String ars[])
	throws IOException,ClassNotFoundException
    {
	Student stu =new Student(19,"dd",60,"hx");
	FileOutputStream tos=new FileOutputStream("met.txt");
	ObjectOutputStream os=new ObjectOutputStream(tos); 
	try
	{
	    os.writeObject(stu);
	    os.close();
	}
	catch(IOException e)
	{
	    System.out.println(e.getMessage());
	}
	stu=null;
	FileInputStream fi=new FileInputStream("met.txt");
	ObjectInputStream si=new ObjectInputStream(fi);
	try
	{
	    stu=(Student)si.readObject();
	    si.close();
	}
	catch(IOException e)
	{
	    System.out.println(e.getMessage());
	}
    System.out.println("ID is"+stu.id);
    System.out.println("name is"+stu.name);
    System.out.println("age is"+stu.age);
    System.out.println("dep is"+stu.dep);
    }
}

class Student implements Serializable
{
    int id;
    String name;
    int age;
    String dep;
    public Student(int id,String name,int age,String dep)
    {
	this.id=id;
	this.name=name;
	this.age=age;
	this.dep=dep;
    }
}
