java课程设计客户管理系统源代码.docx

1、java课程设计客户管理系统源代码 This manuscript was revised by the office on December 22, 2012java课程设计客户管理系统源代码完整代码：1.客户类（class person）：package 客户管理系统; public class Person private int num; private String name; private String address; private String sex; public Person() public Person(int num,String name,String add

2、ress,String sex) this.num=num; this.name=name; this.address=address; this.sex=sex; public void setNum(int num) this.num=num; public int getNum() return num; public void setName(String name) this.name=name; public String getName() return name; public void setAddress(String address) this.address=addre
