Demo

public class Run {
    public static void main(String[] args) throws Exception {
		Cmp2beans cmp2beans=new Cmp2beans();
		Host whiteHost=new Host();
		Host blackHost=new Host();
		
		List whiteDogs=new ArrayList();
		List blackDogs=new ArrayList();
		whiteDogs.add(new Dog("jia",10.5));
		blackDogs.add(new Dog("ji[\\s\\S]*", 10.5));
		
		whiteHost.setAge(30);
		whiteHost.setCat(new Cat("tom", 3));
		whiteHost.setDogs(whiteDogs);
		blackHost.setAge(30);
		blackHost.setCat(new Cat("tom", 2));
		blackHost.setDogs(blackDogs);
		
		cmp2beans.compare(whiteHost, blackHost, true, false);
		
	}
}
