完整代码：
1. 客户类〔class person〕：
package客户管理系统;
publicclass Person {
privateintnum;
private String name;
private String address;
private String sex;

public Person(){}

public Person(intnum,String name,String address,String sex){
this.num=num;
this.name=name;
this.address=address;
this.sex=sex;
}
publicvoid setNum(intnum){
this.num=num;
}
publicint getNum(){
returnnum;
}
publicvoid setName(String name){
this.name=name;
}
public String getName(){
returnname;
}
publicvoid setAddress(String address){
this.address=address;
}
public String getAddress(){
returnaddress;
}
publicvoid setSex(String sex){
this.sex=sex;
}
public String getSex(){
returnsex;
}
public String toString() {
return"\t"+num+"\t"+name+"\t"+address+"\t"+sex;
}

}
2. 菜单类(class Menu)：
package客户管理系统;

import java.util.Scanner;

publicclass Menu {
Scanner input=new Scanner(System.in);
public Menu() {}
publicint showMenu() {
System.out.println("***********************************");
System.out.println("客户管理系统");
System.out.println("===================================");
System.out.println("【1】增加");
System.out.println("【2】删除");
System.out.println("【3】修改");
System.out.println("【4】查询");
System.out.println("【5】浏览");
System.out.println("【6】退出");
System.out.println("***********************************");
System.out.print("请选择操作：");

returninput.nextInt();
}
publicint subMenu() {
System.out.println("\t【查询客户】");
System.out.println("\t[1]按客户编号查询");
System.out.println("\t[2]按客户XX查询");
System.out.println("\t[3]按地址查询");
System.out.println("\t[4]退出");
System.out.println("\t请选择查询编号");
returninput.nextInt();
}

}

3. 实际操作类〔class FileOperate 〕：

//修改

publicvoid update() throws NumberFormatException,IOException{

//退出查询

//浏览
publicvoid shoAll() throws NumberFormatException,IOException{

}
//退出系统
publicboolean exit() {
System.out.println("是否确定退出〔Y/N〕？");
return!"Y".equalsIgnoreCase(input.next())?true:false;
}
}
4. 测试类〔class Text〕:
package客户管理系统;

import java.io.IOException;

publicclass Test {

publicstaticvoid main(String[] args) throws NumberFormatException,
IOException {
Menu m=new Menu();
booleanflag=true;
FileOperate fo=new FileOperate();
while(flag) {
intslt=m.showMenu();
switch(slt) {
case 1:fo.insert();//增加
break;
case 2:fo.delete();//删除
break;
case 3:fo.update();//修改
break;
case 4:fo.search();//查询
break;
case 5:fo.shoAll();//浏览
break;
case 6: //退出
flag=fo.exit();
if(!flag)
System.out.println("谢谢使用！");
break;
}
}
}

}
