JAVA SERIALIZE例子

import java.io.*;

class ObjectSerialTest {
	public static void main(String[] args) throws Exception {
		Employee e1 = new Employee(" zhangsan ", 25, 3000.50);
		Employee e2 = new Employee(" lisi ", 24, 3200.40);
		Employee e3 = new Employee(" wangwu ", 27, 3800.55);

		FileOutputStream fos = new FileOutputStream(" employee.txt ");
		ObjectOutputStream oos = new ObjectOutputStream(fos);
		oos.writeObject(e1);
		oos.writeObject(e2);
		oos.writeObject(e3);
		oos.close();

		FileInputStream fis = new FileInputStream(" employee.txt ");
		ObjectInputStream ois = new ObjectInputStream(fis);
		Employee e;
		for (int i = 0; i < 3; i++) {
			e = (Employee) ois.readObject();
			System.out.println(e.name + " : " + e.age + " : " + e.salary);
		}
		ois.close();
	}
}

class Employee implements Serializable {
	String name;
	int age;
	double salary;
	transient Thread t = new Thread();

	public Employee(String name, int age, double salary) {
		this.name = name;
		this.age = age;
		this.salary = salary;
	}

	private void writeObject(java.io.ObjectOutputStream oos) throws IOException {
		oos.writeInt(age);
		oos.writeUTF(name);
		System.out.println(" Write Object ");
	}

	private void readObject(java.io.ObjectInputStream ois) throws IOException {
		age = ois.readInt();
		name = ois.readUTF();
		System.out.println(" Read Object ");
	}
