小弟最近在学习Java1.8下关于浅Clone与深Clone的区别。发现有一些与以前不同的地方感觉已经没有浅Clone这一说法重载Clone方法后对Clone后的对象方法赋值已经不会改变原Clone对象难道在Java1.8中取消了浅Clone？请各位大神指点

你这个验证做的有问题，基本类型深浅克隆都不会改变原对象的值，你可以在你的JavaBean里面再加一个对象的变量，然后验证下是否给这个对象的字段赋值会改变原对象里同样的值

浅克隆，依次复制一个对象的每个字段。
深克隆，如果一个对象的字段是引用的话，那么不是简单指向同一个对象，而是创建一个新的对象，然后再递归复制这个字段对象其中的每个字段。

好像是改了，我的也是

    // 測試克隆模式
    public static void main(String[] args) throws Exception {
        Sheep sheep = new Sheep("duoli", new Date(4554545454l));
        Sheep sheep2 = (Sheep) sheep.clone();

        System.out.println(sheep.getName());
        System.out.println(sheep.getBirthday().getTime());

        System.out.println(sheep2.getName());
        System.out.println(sheep2.getBirthday().getTime());

        System.out.println("-----------------------------");
        System.out.println("-----sheep.setBirthday(new Date(321321321l))");

        sheep.setBirthday(new Date(321321321l));

        System.out.println(sheep.getName());
        System.out.println(sheep.getBirthday().getTime());

        System.out.println(sheep2.getName());
        System.out.println(sheep2.getBirthday().getTime());

    }

输出结果:
duoli
4554545454
duoli

4554545454

-----sheep.setBirthday(new Date(321321321l))
duoli
321321321
duoli
4554545454
