java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 address,String sex){ this.num=num;

=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){

=name;

}

public String getName(){

return name;

}

public void setAddress(String address){ this.address=address;

}

public String getAddress(){

return address;

}

public void setSex(String sex){

this.sex=sex;

}

public String getSex(){

return sex;

}

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;

public class Menu {

Scanner input=new Scanner(System.in);

public Menu() {}

public int 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：");

return input.nextInt();

}

public int 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]按客户姓名查询");

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");

return input.nextInt();

}

}

3.实际操作类（class FileOperate ）：package客户管理系统;

import java.io.BufferedReader;

import java.io.File;

import java.io.FileNotFoundException; import java.io.FileReader;

import java.io.IOException;

import java.io.PrintWriter;

import java.util.ArrayList;

import java.util.List;

import java.util.Scanner;

public class FileOperate {

private static String INFO="D:/info.dat";

File file = new File(INFO);

Scanner input=new Scanner(System.in);

public FileOperate() {

if (!file.exists()) {

try {

file.createNewFile();

}catch(IOException e) {

e.printStackTrace();

}

}

}

public List getList() throws NumberFormatException,IOException{ BufferedReader br=new BufferedReader(new FileReader(file));

String msg=null;

List list =new ArrayList();

while ((msg =br.readLine())!=null) {
