java实现客户管理系统（用户管理系统java）

本文实例为大家分享了java实现客户管理系统的具体代码，供大家参考，具体内容如下

代码:

先写个客户类

package jjave_16;

/**

* 客户类

*

*/

public class Customer {

private String name;

private char gender;

private int age;

private String phone;

private String email;

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;

}

public String toString() {

return "Customer [name=" + name + ", gender=" + gender + ", age=" + age + ", phone=" + phone + ", email=" + email + "]";

}

}

之后就写两个工具类和运行类

package jjave_16;

/**

* 工具类:操作字符长度输入是否正确

*

*/

import java.util.Scanner;

public class CMUtility {

/**

* 用于界面菜单的选择,该方法读取键盘,如果用户输入1-5中的任意字符,则方法返回,返回值为用户键入字符

*/

private static Scanner scan=new Scanner(System.in);//少了static，下面的方面无法使用

public static char readMenuSelection() {

char c;

for(;;) {

String str=readKeyBoard(1,false);

c=str.charAt(0);

if(c!='1'&&c!='2'&&c!='3'&&c!='4'&&c!='5') {

System.out.println("选择错误,请重新输入:");

}else break;

}

return c;

}

/**

*

* @param

* @param blankReturn

* @return

*/

public static String readKeyBoard(int limit, boolean blankReturn) {

String line=" ";

for(;;) {

line=scan.nextLine();

if(line.length()==0) {

if(blankReturn)

return line;

}

if(line.length()<1||line.length()>limit) {

System.out.println("输入长度(在大于)" + limit + ")错误,请重新输入:");

//continue;

}else break;

}

return line;

}

/**

* 功能5: 退出判断

*/

public static char readConfirmSelection() {

char c;

for(;;) {

String str=readKeyBoard(1,false).toUpperCase();

c=str.charAt(0);

if(c!='Y'&&c!='N') {

System.out.println("选择错误,请重新输入:");

}else break;

}

return c;

}

/**

* 从键盘读取一个长度不超过limit的字符串,并将其作为方法的返回值

*/

public static String readString(int i) {

return readKeyBoard(i,false);

}

/**

* 从键盘读取一个字符,并将其作为方法的返回值

*/

public static char readChar() {

char c;

for (;;) {

String str = readKeyBoard(1, false);

c = str.charAt(0);

if (c == '男' || c == '女') {

break;

} else {

System.out.println("输入错误(只能选择男或女),请重新输入:");

}

}

return c;

}

/**

* 从键lTwHNqrOc盘读取一个长度不超过2位的整数,并将其作为方法的返回值

*/

public static int readInt() {

int n;

for (;;) {

String str = readKeyBoard(2, false);

try {

n = Integer.parseInt(str);

break;

} catch (Exception e) {

System.out.println("数字输入错误,请重新输入:");

}

}

return n;

}

}

package jjave_16;

/**

*/

public class CustomerList {

private Customer[] customers;

}

return custs;

}

public Customer getCustomer(int limit) {

}else return null;

}

public boolean addCustomer(Customer cust) {

/**

*/

if(total>customers.length)return false;

return true;
