java课程设计客户管理系统源代码 完整代码： 1.客户类（classperson）： package客户管理系统; publicclass Person privateint num; private String name; private String address; private String sex; public Person() public Person(int num,String name,String address,String sex) this.num=num; =name; this.address=address; this.sex=sex; publicvoid setNum(int num) this.num=num; publicint getNum() return num; publicvoid setName(String name) =name; public StringgetName() return name; publicvoid setAddress(String address) this.address=address;
