IO流 使用properties 类读取配置文件，构建文件，序列化和反序列化

dog.properties

name=tom
age=5
color=red

public class Homework03{
	public static void main(string[] args) throws IOException {
		
		String filePath = "src\dog.properties";
		Properties properties = new Properties();
		properties.load(new FildReader(filePath));
		String name = properties.get("name") + "";//Object -> String
		int age = Integer.parseInt(properties.get("age") + "");//Object -> int
		String color = properties.get("color") + "";//Object -> String

		new dog = new Dog(name, age, color);
		System.out.println("===dog对象信息===");
		System.out.println(dog);

		//序列化
		String serFilePath = "e:\dog.dat";
		ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(serFilePath));
		oos.writeObject(dog);
		//关闭流
		oos.close();
		System.out.println("dog对象序列化完成..");
	}
	
	//（4）反序列化
	//在编写一个方法，反序列化dog
	public void m1(){
		String serFilePath = "e:\dog.dat";
		ObjectInputStream ois = new ObjectInputStream(new FileInputStream(serFilePath ));
		Dog dog = (Dog) ois.readObject();
		
		System.out.println("===反序列化后 dog===");
		System.out.println(dog);
		
		ois.close();
	}
}

//Dog类，必须实现Serializable接口
class Dog implements Serializable{
	private string name;
	private int age;
	private string color;

	public Dog(String name, int age, String color){
		this.name = name;
		this.age = age;
		this.color = color;
	}

	@Override
	public String toString(){
		return "Dog{" +
				"name='" + name +''' +
				", age=" + age +
				", color='" + color + ''' +
				'}'; 
	}
	
}
