Customer类:

publicclassCustomer{/***@name客户姓名*@sex性别*@age年龄*@phone电话号码*@email邮箱*/privateStringname;privateStringsex;privateintage;privateStringphone;privateStringemail;publicCustomer(){};publicCustomer(Stringname,Stringsex,intage,Stringphone,Stringemail){this.name=name;this.sex=sex;this.age=age;this.phone=phone;this.email=email;}publicStringgetName(){returnthis.name;}publicvoidsetName(Stringname){this.name=name;}publicStringgetSex(){returnthis.sex;}publicvoidsetSex(Stringsex){this.sex=sex;}publicStringgetPhone(){returnphone;}publicvoidsetPhone(Stringphone){this.phone=phone;}publicintgetAge(){returnthis.age;}publicvoidsetAge(intage){this.age=age;}publicStringgetEmail(){returnthis.email;}publicvoidsetEmail(Stringemail){this.email=email;}}

CustomerList 类:

publicclassCustomerList{privateCustomer[]customers;privatestaticinttotal=0;/***构造器初始化对象数组*@paramtotalCustmoers客户的总数*/publicCustomerList(inttotalCustmoers){customers=newCustomer[totalCustmoers];}/***增加客户*@paramcustomer客户*@return返回是否添加成功*/publicbooleanaddCustomer(Customercustomer){if(customer!=null&&total<customers.length){customers[total]=customer;total++;returntrue;}else{returnfalse;}}/***替换*@paramindex指定的客户的编号*@paramcust修改的客户*@return返回是否修改成功*/publicbooleanreplaceCustomer(intindex,Customercust){if(index>=0&&index<total){customers[index]=cust;returntrue;}else{returnfalse;}}/***删除客户*@paramindex指定的客户的编号*@return返回是否删除成功*/publicbooleandeleteCustomer(intindex){if(index<customers.length){for(inti=index;i<total-1;i++){customers[i]=customers[i+1];/**把数据往前挪动*/}customers[total-1]=null;total--;/**存储的数据的总数-1*/returntrue;}else{returnfalse;}}/***展现客户的信息*@paramindex*@return返回客户*/publicCustomergetCustomer(intindex){if(index>=0&&index<total){returncustomers[index];}else{returnnull;}}/***获取所有的客户*@return客户*/publicCustomer[]getAllCustomers(){Customer[]cust=newCustomer[total];/**新建一个数组来接收原数组的数据*/for(inti=0;i<total;i++){cust[i]=customers[i];}returncust;}/***得到客户的总数*@return*/publicintgetTotal(){returntotal;}}

CustomerVIew类:

publicclassCustomerView{privateCustomerListcustomerList=newCustomerList(10);/***显示主菜单*/publicvoidenterMainMenu(){while(true){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("-----------------------------------------------------");Scannerinput=newScanner(System.in);intop=input.nextInt();switch(op){case1:this.addNewCustomer();break;case2:this.modifyCustomer();break;case3:this.deleteCustomer();break;case4:this.listAllCustomers();break;case5:System.exit(0);break;default:System.out.println("重新选择功能");break;}}}/***增加客户*/privatevoidaddNewCustomer(){/***从键盘处接收客户数据*/System.out.println("-------------------添加客户-------------------");Scannerinput=newScanner(System.in);System.out.println("姓名:");Stringname=input.next();System.out.println("性别:");Stringsex=input.next();System.out.println("年龄:");intage=input.nextInt();System.out.println("电话号码:");Stringphone=input.next();System.out.println("电子邮箱:");Stringemail=input.next();/***对客户数据进行封装*/Customerperson=newCustomer(name,sex,age,phone,email);Booleanflag=customerList.addCustomer(person);if(flag){System.out.println("-------------------添加成功-------------------");}else{System.out.println("-------------------添加失败-------------------");}}/***修改客户信息*/privatevoidmodifyCustomer(){System.out.println("-------------------修改客户-------------------");System.out.println("要修改的客户id:");Scannerinput=newScanner(System.in);intnumber=input.nextInt();Customercustomer=customerList.getCustomer(number);System.out.println("姓名:"+customer.getName());Stringname=CMUtility.readString(5,customer.getName());System.out.println("性别:"+customer.getSex());Stringsex=CMUtility.readString(5,customer.getSex());System.out.print("年龄("+customer.getAge()+"):");intage=CMUtility.readInt(customer.getAge());System.out.print("电话("+customer.getPhone()+"):");Stringphone=CMUtility.readString(13,customer.getPhone());System.out.print("邮箱("+customer.getEmail()+"):");Stringemail=CMUtility.readString(15,customer.getEmail());/**得到新的客户数据*/customer=newCustomer(name,sex,age,phone,email);Booleanflag=customerList.replaceCustomer(number,customer);if(flag){System.out.println("-------------------修改成功-------------------");}else{System.out.println("-------------------修改失败-------------------");}}/***删除客户*/privatevoiddeleteCustomer(){System.out.println("-------------------删除客户-------------------");System.out.println("要删除的客户id:");Scannerinput=newScanner(System.in);intnumber=input.nextInt();while(true){System.out.println("退出(-1)");if(number>=0&&number<customerList.getTotal()){System.out.println("找到指定客户");}elseif(number==-1){return;}else{System.out.println("输入错误");break;}}System.out.println("是否确认删除该客户?Y/N");Stringch=input.next();charo=ch.charAt(0);if(o=='Y'){booleanflag=customerList.deleteCustomer(number);if(flag){System.out.println("-------------------删除成功-------------------");}else{System.out.println("-------------------删除失败-------------------");}}else{return;}}/***获取客户列表*/privatevoidlistAllCustomers(){Customer[]customer=customerList.getAllCustomers();if(customer.length==0){System.out.println("没有任何客户数据");}else{for(inti=0;i<customer.length;i++){System.out.println("姓名:"+customer[i].getName()+""+"性别"+customer[i].getSex()+""+"年龄:"+customer[i].getAge()+""+"电话号码:"+customer[i].getPhone()+""+"电子邮箱:"+customer[i].getEmail()+"");}}}publicstaticvoidmain(String[]args){CustomerViewco=newCustomerView();co.enterMainMenu();}}

工具类：

publicclassCMUtility{privatestaticScannerscanner=newScanner(System.in);publicstaticStringreadString(intlimit){returnreadKeyBoard(limit,false);}publicstaticintreadInt(intdefaultValue){intn;for(;;){Stringstr=readKeyBoard(2,true);if(str.equals("")){returndefaultValue;}try{n=Integer.parseInt(str);break;}catch(NumberFormatExceptione){System.out.print("数字输入错误，请重新输入：");}}returnn;}
