SerializableDemo 一个java序列化的例子

序列化在很多地方都会用到，可以传输对象。下面是一个简单的本地存储的序列化例子。
代码：

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


public class SerializableDemo {
	public static void main(String[] args) throws Exception{
		new Bak("11231231","as5d45asd",1,0).backup();
		Bak bak = Bak.recover();

		System.out.println(bak.account);
		System.out.println(bak.password);
		System.out.println(bak.remPassword);
		System.out.println(bak.autoLogin);
	}
}


class Bak implements Serializable {
	/**
	 *
	 */
	private static final long serialVersionUID = 1L;
	public String account;
	public String password;
	public int remPassword;
	public int autoLogin;
	Bak(String account,String password,int remPassword,int autoLogin) {
		this.account = account;
		this.password = password;
		this.remPassword = remPassword;
		this.autoLogin = autoLogin;
	}
	public void backup () throws Exception{
		File file = new File("C:"+File.separator+"WINDOWS"+File.separator+"qsuron.bak");
		ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(file));
		oos.writeObject(this);
		oos.close();
	}
	public static Bak recover () throws Exception{
		File file = new File("C:"+File.separator+"WINDOWS"+File.separator+"qsuron.bak");
		ObjectInputStream ois = new ObjectInputStream(new FileInputStream(file));
		Bak bak = (Bak)ois.readObject();
		ois.close();
		return bak;
	}
}

例子输出：
