某销售管理系统设计并实现一个客户类Customer,在该类中包含姓名、电话以及存储客户地址的成员变量,客户地址的类型为Address,用浅克隆和深克隆分别实现Customer对象的复制,并比较这两种克隆方式的异同。 要求: 1、画出UML图(浅克隆和深克隆);

以下是浅克隆和深克隆的UML图:
浅克隆UML图:
```
+-----------------+
| Customer |
+-----------------+
| - name: String |
| - phone: String |
| - address: Address|
+-----------------+
| + getName(): String|
| + setName(name: String): void|
| + getPhone(): String|
| + setPhone(phone: String): void|
| + getAddress(): Address|
| + setAddress(address: Address): void|
| + clone(): Customer|
+-----------------+
+-----------------+
| Address |
+-----------------+
| - street: String |
| - city: String |
| - state: String |
| - zipCode: String|
+-----------------+
| + getStreet(): String|
| + setStreet(street: String): void|
| + getCity(): String|
| + setCity(city: String): void|
| + getState(): String|
| + setState(state: String): void|
| + getZipCode(): String|
| + setZipCode(zipCode: String): void|
+-----------------+
```
深克隆UML图:
```
+-----------------+
| Customer |
+-----------------+
| - name: String |
| - phone: String |
| - address: Address|
+-----------------+
| + getName(): String|
| + setName(name: String): void|
| + getPhone(): String|
| + setPhone(phone: String): void|
| + getAddress(): Address|
| + setAddress(address: Address): void|
| + clone(): Customer|
+-----------------+
+-----------------+
| Address |
+-----------------+
| - street: String |
| - city: String |
| - state: String |
| - zipCode: String|
+-----------------+
| + getStreet(): String|
| + setStreet(street: String): void|
| + getCity(): String|
| + setCity(city: String): void|
| + getState(): String|
| + setState(state: String): void|
| + getZipCode(): String|
| + setZipCode(zipCode: String): void|
| + clone(): Address|
+-----------------+
```
在上面的UML图中,Customer类有一个Address对象作为其成员变量。在浅克隆中,当我们克隆一个Customer对象时,它的Address对象只是通过引用复制到新对象中。这意味着新对象和原对象都引用同一个Address对象。而在深克隆中,我们在复制Customer对象时,同时也会复制其Address对象。这意味着新对象会拥有一个全新的Address对象,而不是引用原对象中的Address对象。
