    public String sex    = "male";
    public String variety = "Husky";
    public int age    = 3;
    public String name   = "dooooooogy";
    public void eat(String food){
        System.out.println(name + "在吃" +food);
    }
    public void sleep(){
        System.out.println(name + "睡得很香");
    }
    public String bark(){
        return "wangwang!";
    }
    public void watchHouse(){
