java實(shí)現(xiàn)簡(jiǎn)單的客戶信息管理系統(tǒng)
本文實(shí)例為大家分享了java實(shí)現(xiàn)簡(jiǎn)單客戶信息管理系統(tǒng)的具體代碼,供大家參考,具體內(nèi)容如下
全篇文章開(kāi)源,源碼供讀者使用。這是一篇關(guān)于java的客戶信息管理系統(tǒng)的文章,里面簡(jiǎn)單實(shí)現(xiàn)了數(shù)據(jù)庫(kù)管理系統(tǒng)的基本功能,可以算是算筆者的學(xué)習(xí)筆記,也為大家學(xué)習(xí)提供便利。所以代碼都是在一個(gè)包下完成的,所以沒(méi)有使用導(dǎo)包的操作,省去了外賣project的申明,剩下的就寫的文章里了。話不多說(shuō),看文章吧。
首先給大家看一下總的操作界面(別看簡(jiǎn)單,里面的還是有東西的),后面就附上實(shí)現(xiàn)源碼、要求和注釋
Customer類
下面是關(guān)于Customer類的編寫要求:
* 用來(lái)封裝客戶的以下信息
* Sting name
* int age
* char gender
* Stirng phone
* String email
* 提供getset方法
* 構(gòu)造器自行設(shè)定
public class Customer { ?? ?private String name; ?? ?private int age; ?? ?private String gender; ?? ?private String phone; ?? ?private String email; ?? ? ?? ?public Customer() { ?? ??? ? ?? ?} ?? ? ?? ?public Customer(String name,int age,String gender,String phone,String email) { ?? ??? ?this.name = name; ?? ??? ?this.age = age; ?? ??? ?this.gender = gender; ?? ??? ?this.phone = phone; ?? ??? ?this.email = email; ?? ?} ?? ? ?? ?public String getName() { ?? ??? ?return name; ?? ?} ?? ?public void setName(String name) { ?? ??? ?this.name = name; ?? ?} ?? ?public int getAge() { ?? ??? ?return age; ?? ?} ?? ?public void setAge(int age) { ?? ??? ?this.age = age; ?? ?} ?? ?public String getGender() { ?? ??? ?return gender; ?? ?} ?? ?public void setGender(String gender) { ?? ??? ?this.gender = gender; ?? ?} ?? ?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; ?? ?} ?? ? }
CustomerList類
下面是關(guān)于CustomerList類的編寫要求:
* CustomerList類的設(shè)計(jì)
* Customer[] 用來(lái)保存客戶信息
* int total 用來(lái)保存當(dāng)前存入客戶數(shù)量
* 該類至少提供以下的構(gòu)造器和方法
* public CustomerLIst(int totalCustomer);
* public boolean addCustomer(Customer customer);
* public boolean replaceCustomer(int index,Customer cust);
* public boolean deleteCustomer(int index);
* public Customer[] getallCustomer();
* public Customer getCustomer(int index);
* public int getToal();
public class CustomerList { ?? ?private static Customer customers[]; ?? ?private static int total; ?? ? ?? ?public CustomerList(int totalCustomer) { ?? ??? ?customers = new Customer[totalCustomer]; ?? ?} ?? ? ?? ?// 添加客戶 ?? ?public boolean addCustomer(Customer customer) { ?? ??? ?if(total >= customers.length) { ?? ??? ??? ?return false; ?? ??? ?} ?? ??? ?customers[total++] = customer; ?? ??? ?return true; ?? ?} ?? ? ?? ?// 修改指定位置的客戶信息 ?? ?public boolean replaceCustomer(int index,Customer cust) { ?? ??? ?if(index < 0 || index >= total) { ?? ??? ??? ?return false; ?? ??? ?} ?? ??? ?customers[index] = cust; ?? ??? ?return true; ?? ?} ?? ? ?? ?// 刪除指定位置的客戶 ?? ?public boolean deleteCustomer(int index) { ?? ??? ?if(index < 0 || index >= total) { ?? ??? ??? ?return false; ?? ??? ?} ?? ??? ?for(int i = index;i < total - 1;i++) { ?? ??? ??? ?customers[i] = customers[i+1]; ?? ??? ?} ?? ??? ?customers[total - 1] = null; ?? ??? ?total--; ?? ??? ?return true; ?? ?} ?? ? ?? ?// 得到所有客戶的信息 ?? ?public static Customer[] getallCustomer() { ?? ??? ?Customer[] custs = new Customer[total]; ?? ??? ?for(int i = 0;i < total;i++) { ?? ??? ??? ?custs[i] = customers[i]; ?? ??? ?} ?? ??? ?return custs; ?? ?} ?? ? ?? ?// 得到指定客戶的信息 ?? ?public Customer getCustomer(int index) { ?? ??? ?if(index < 0 || index >= total) { ?? ??? ??? ?return null; ?? ??? ?} ?? ??? ?return customers[index]; ?? ?} ?? ? ?? ?// 得到Customers中所有客戶的個(gè)數(shù) ?? ?public static int getTotal() { ?? ??? ?return total; ?? ?} ?? ? }
CustomerView類
CustomerView類的編寫
* 主模塊:用于用戶界面的展示、與用戶交互
* CustomerList customerList = new CustomerList(10)
* 應(yīng)含有的構(gòu)造器和方法
* private void enterMainMenue()
* private void addNewCustomer()
* private void modifyCustomer()
* private void deleteCustomer()
* private void listAllCustomers()
* private static void main(String[] args)
