client.java.svn-base

这个是我做j2ee培训时候自己整理和编写的设计模式的学习例子

package org.hyq.observer0;
public class Client  {
	public static void main(String[] args) {	
		DataSubject bag = new DataSubject();
		DataObserver1 do1 = new DataObserver1(bag);
		DataObserver2 do2 = new DataObserver2(bag);
		// adder and printer add themselves to the bag
		System.out.println("About to add another integer to the bag:");
		bag.add("aNewCar");
		System.out.println();
		System.out.println("About to remove an integer from the bag:");
		bag.remove(0);
	}
}
