设计模式-?状态模式

感觉就是策略模式啊....

class SContext{
    private Weather weather;

    public void setWeather(Weather weather) {
        this.weather = weather;
    }

    public Weather getWeather() {
        return weather;
    }
    public String WeatherMessage(){
        return weather.getWeather();
    }
}
interface Weather{
    String getWeather();
}
//concreteStatsubClass
class Rain implements Weather{

    @Override
    public String getWeather() {
        return "rain";
    }
}

class Sunshine implements Weather{
    @Override
    public String getWeather() {
        return "sunshine";
    }
}
public class StateTest {
    public static void main(String[] args){
        SContext context = new SContext();
        context.setWeather(new Sunshine());
        System.out.println(context.WeatherMessage());

        SContext context1 = new SContext();
        context1.setWeather(new Rain());
        System.out.println(context1.WeatherMessage());
    }
}
