編寫java代碼要求顧客輸入購買多少斤當(dāng)用戶輸入為10斤以內(nèi)，則輸出用戶應(yīng)支付金額？

2、public class Test11 {

public static void main(String[] args) {

System.out.println("滯貿(mào)旅客的人數(shù)" + (1189 - 108*10) );

}

}

3、public class Test11 {

public static void main(String[] args) {

try {

Scanner scanner = new Scanner(System.in);

System.out.print("輸入購買雞蛋（斤）：");

int number = scanner.nextInt();

if(number10){

throw new RuntimeException("不允許購買這么多！");

}

else {

System.out.println("用戶應(yīng)支付金額"+number*3.98);

}

}

catch (Exception e){

System.out.println(e.getMessage());

}

}

}

用JAVA編寫購物系統(tǒng)的代碼是什么？（急）

算是最簡單的吧

package cn.job01;

import java.util.Scanner;

public class Lx07 {

public static void choice() {

System.out.println("登陸菜單 ");

System.out.println("1登陸系統(tǒng)");

System.out.println("2退出");

}

static void choice1() {

System.out.println("購物管理系統(tǒng)客戶信息");

System.out.println("1顯示所有客戶信息");

System.out.println("2添加客戶信息");

System.out.println("3修改客戶信息");

System.out.println("4查詢客戶信息");

}

static void choice2() {

System.out.println("購物管理系統(tǒng)真情回饋");

System.out.println("1幸運(yùn)大放送");

System.out.println("2幸運(yùn)抽獎(jiǎng)");

System.out.println("3生日問候");

}

public static void main(String[] args) {

choice();

Scanner input = new Scanner(System.in);

System.out.println("請輸入1or2");

int num = input.nextInt();

switch (num) {

case 1:

System.out.println("主菜單");

System.out.println("1客戶信息管理");

System.out.println("2購物結(jié)算");

System.out.println("3真情回饋");

System.out.println("4注銷");

break;

}

System.out.println("選擇輸入數(shù)字");

int num1 = input.nextInt();

switch (num1) {

case 1:

choice1();

break;

case 2:

System.out.println("購物結(jié)算");

break;

case 3:

choice2();

break;

case 4:

choice();

break;

}

}

}
