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!
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");
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");
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;
}
}
}
