大家好,今天来为大家分享java购物系统代码的一些知识点,和java的问题解析,大家要是都明白,那么可以忽略,如果不太清楚的话可以看看本篇文章,相信很大概率可以解决您的问题,接下来我们就一起来看看吧!

java购物系统代码(java)

用JAVA编写购物系统的代码是什么(急)

算是最简单的吧

package cn.job01;

import java.util.Scanner;

public class Lx07{

public static void choice(){

System.out.println("登陆菜单");

java购物系统代码(java)

System.out.println("1登陆系统");

System.out.println("2退出");

}

static void choice1(){

System.out.println("购物管理系统>客户信息");

System.out.println("1显示所有客户信息");

java购物系统代码(java)

System.out.println("2添加客户信息");

System.out.println("3修改客户信息");

System.out.println("4查询客户信息");

}

static void choice2(){

System.out.println("购物管理系统>真情回馈");

System.out.println("1幸运大放送");

System.out.println("2幸运抽奖");

System.out.println("3生日问候");

}

public static void main(String[] args){

choice();

Scanner input= new Scanner(System.in);

System.out.println("请输入1or2");

int num= input.nextInt();

switch(num){

case 1:

System.out.println("主菜单");

System.out.println("1客户信息管理");

System.out.println("2购物结算");

System.out.println("3真情回馈");

System.out.println("4注销");

break;

}

System.out.println("选择输入数字");

int num1= input.nextInt();

switch(num1){

case 1:

choice1();

break;

case 2:

System.out.println("购物结算");

break;

case 3:

choice2();

break;

case 4:

choice();

break;

}

}

}
