Java实战之客户信息管理系统

这篇文章主要介绍了Java实战之客户信息管理系统,文中有非常详细的代码示例,对正在学习java的小伙伴们有非常好的帮助,需要的朋友可以参考下

一、软件设计结构

对于初学者来说，弄清框架显得尤为重要

首先该软件有以下三种模块组成

二、MVC设计模式

模型层：Customer处理数据

控制层：CustomerList处理业务逻辑

视图层：CustomerView显示数据

以下三点建议结合代码理解

1.Customer为实体对象，用于封装客户信息

2.CustomerList为Customer对象的管理模块，内部用数组管理一组Customer对象，并提供相应的添加、修改、删除和遍历的方法，供CustomerView调用

3.CustomerView为主模块，负责菜单的显示和处理用户操作

四个类都在同一包下

三、Customer

package org.atjinzhao.customer; public class Customer { private String name;//姓名 private char gender;//性别 private int age;//年龄 private String phone;//电话 private String email;//邮箱 public Customer() { } public Customer(String name, char gender, int age, String phone, String email) { this.name = name; this.gender = gender; this.age = age; this.phone = phone; this.email = email; } public String getName() { return name; } public void setName(String name) { this.name = name; } public char getGender() { return gender; } public void setGender(char gender) { this.gender = gender; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getPhone() { return phone; } public void setPhone(String phone) { this.phone = phone; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } }

四、CustomerList

package org.atjinzhao.customer; public class CustomerList { private Customer[] customers;//客户列表 private int total = 0;//记录已保存顾客数量 //构造器 public CustomerList(int totalCustomer) { customers = new Customer[totalCustomer]; } //方法 /** * 添加客户 * return：true添加成功，false：添加失败 */ public boolean addCustomer(Customer customer){ if (total = total) { return false; }else{ customers[index] = cust; return true; } } /** * 删除指定索引位置上的客户 * @param index * @return true删除成功 false删除失败 */ public boolean deleteCustomer(int index){ if (index >= 0 && index = 0 && index

五、CustomerView

package org.atjinzhao.customer; public class CustomerView { private CustomerList customerList = new CustomerList(10); public CustomerView() { Customer cust = new Customer("李明",'男',19,"12349982563","lm@gmail.com"); customerList.addCustomer(cust); } public void enterMainMenu(){ //显示主页面 boolean isFlag = true; while(isFlag){ System.out.println("-----------------客户信息管理软件-----------------"); System.out.println(" 1 添加客户"); System.out.println(" 2 修改客户 "); System.out.println(" 3 删除客户 "); System.out.println(" 4 客户列表 "); System.out.println(" 5 退出 "); System.out.println(" 请选择（1-5）： "); char selection = CMUtility.readMenuSelection(); switch (selection) { case '1': addNewCustomer(); break; case '2': modifyCustomer(); break; case '3': deleteCustomer(); break; case '4': listAllCustomers(); break; case '5': System.out.print("是否确认退出（Y/N）："); char isExit = CMUtility.readConfirmSelection(); if (isExit == 'Y') { isFlag = false; } } } } /** * 添加客户 */ public void addNewCustomer(){ System.out.println("-----------------添加客户-----------------"); System.out.print("姓名："); String name = CMUtility.readString(10); System.out.print("性别："); char gender = CMUtility.readChar(); System.out.print("年龄："); int age = CMUtility.readInt(); System.out.print("电话："); String phone = CMUtility.readString(13); System.out.print("邮箱："); String email = CMUtility.readString(30); Customer customer = new Customer(name,gender,age,phone,email); boolean isSuccess = customerList.addCustomer(customer); if(isSuccess){ System.out.println("-----------------添加成功-----------------"); }else{ System.out.println("---------------目录已满，添加失败---------------"); } } /** * 修改客户 */ public void modifyCustomer(){ System.out.pr上一篇：java实现文件切片和合并的代码示例下一篇：java在文件尾部追加内容的简单实例热门搜索：
