Customer类:

public class Customer {    /**     * @name 客户姓名     * @sex 性别     * @age 年龄     * @phone 电话号码     * @email 邮箱     */    private String name;    private String sex;    private int age;    private String phone;    private String email;    public Customer(){};    public Customer(String name,String sex,int age,String phone,String email){        this.name=name;        this.sex=sex;        this.age=age;        this.phone=phone;        this.email=email;    }    public String getName(){        return this.name;    }    public void setName(String name){        this.name=name;    }    public String getSex(){        return this.sex;    }    public void setSex(String sex){        this.sex=sex;    }    public String getPhone(){        return phone;    }    public void setPhone(String phone){        this.phone=phone;    }    public int getAge(){        return this.age;    }    public void setAge(int age){        this.age=age;    }    public String getEmail(){        return this.email;    }    public void setEmail(String email){        this.email=email;    }}

CustomerList 类:

public class CustomerList {        private Customer [] customers;        private static int total = 0;    /**     * 构造器初始化对象数组     * @param totalCustmoers 客户的总数     */    public CustomerList(int totalCustmoers){        customers = new Customer[totalCustmoers];    }    /**     * 增加客户     * @param customer 客户     * @return 返回是否添加成功     */        public boolean addCustomer(Customer customer){            if(customer!=null&&total=0 && index =0 && index
CustomerVIew类:
public class CustomerView {    private CustomerList customerList = new CustomerList(10);    /**     * 显示主菜单     */    public void enterMainMenu(){        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("-----------------------------------------------------");            Scanner input = new Scanner(System.in);            int op = input.nextInt();            switch(op)            {                case 1 :this.addNewCustomer();break;                case 2 :this.modifyCustomer();break;                case 3 :this.deleteCustomer();break;                case 4 :this.listAllCustomers();break;                case 5 :System.exit(0);break;                default:                    System.out.println("重新选择功能");break;            }        }    }    /**     * 增加客户     */    private void addNewCustomer(){        /**         * 从键盘处接收客户数据         */        System.out.println("-------------------添加客户-------------------");        Scanner input = new Scanner(System.in);        System.out.println("姓名:");        String name = input.next();        System.out.println("性别:");        String sex=input.next();        System.out.println("年龄:");        int age = input.nextInt();        System.out.println("电话号码:");        String phone = input.next();        System.out.println("电子邮箱:");        String email = input.next();        /**         * 对客户数据进行封装         */        Customer person = new Customer(name,sex,age,phone,email);        Boolean flag=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     */    private void modifyCustomer(){        System.out.println("-------------------修改客户-------------------");        System.out.println("要修改的客户id:");        Scanner input = new Scanner(System.in);        int number = input.nextInt();            Customer customer = customerList.getCustomer(number);        System.out.println("姓名:"+customer.getName());        String name = CMUtility.readString(5,customer.getName());        System.out.println("性别:"+customer.getSex());        String sex = CMUtility.readString(5,customer.getSex());        System.out.print("年龄(" + customer.getAge() + "):");        int age = CMUtility.readInt(customer.getAge());        System.out.print("电话(" + customer.getPhone() + "):");        String phone = CMUtility.readString(13, customer.getPhone());        System.out.print("邮箱(" + customer.getEmail() + "):");        String email = CMUtility.readString(15, customer.getEmail());        /**得到新的客户数据*/        customer = new Customer(name,sex,age,phone,email);        Boolean flag = 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     */    private void deleteCustomer(){        System.out.println("-------------------删除客户-------------------");        System.out.println("要删除的客户id:");        Scanner input = new Scanner(System.in);        int number = input.nextInt();        while(true){            System.out.println("退出(-1)");        if(number>=0 && number
工具类：
public class CMUtility {        private static Scanner scanner = new Scanner(System.in);           public static String readString(int limit) {            return readKeyBoard(limit, false);        }           public static int readInt(int defaultValue) {            int n;            for (; ; ) {                String str = readKeyBoard(2, true);                if (str.equals("")) {                    return defaultValue;                }                try {                    n = Integer.parseInt(str);                    break;                } catch (NumberFormatException e) {                    System.out.print("数字输入错误，请重新输入：");                }            }            return n;        }
