currentconditionsdisplay.java

设计模式中的Observer模式。有一气象台例子说明。

package DP.Chapter2;

public class CurrentConditionsDisplay implements Observer, DisplayElement {
	
	private float temperature;
	private float humidity;
	private Subject weatherData;

	public CurrentConditionsDisplay(Subject weatherData) {
		this.weatherData = weatherData;
		weatherData.registerObserver(this);	
	}

	public void update(float temp, float humidity, float pressure) {
		// TODO Auto-generated method stub

	}
	
	public void display() {
		// TODO Auto-generated method stub

	}

}
