        Cat one = new Cat();
        Cat two = one;　　//此时 two 和 one 都指向同一个实例化的对象

        System.out.println("名字：" + one.name);
        System.out.println("年龄：" + one.month);
        System.out.println("体重：" + one.weight);
        System.out.println("品种：" + one.species);
        System.out.println("-----------------------------");
        System.out.println("名字：" + two.name);
