用java编写一个程序：由车牌号前2位知道车辆所属地 浙江省的市就行

package demo

import java.util.Scanner

public class CarCard {

//浙A 杭腔猛闷州，浙B 宁波，浙C 温州，浙D 绍兴，浙E 湖州，浙F 嘉兴，浙G 金华，浙H 衢州，浙J 台州，浙K 丽水，浙L 舟山

//网上搜的，应该是对的，这个东西应该管你要

public static void main(String[] args) {

System.out.println("请输入车牌号")

Scanner sc = new Scanner(System.in)

String carno = sc.next()

String t = carno.substring(0,2)

checkAddressByCarCard(t)

}

private static void checkAddressByCarCard(String no){

String a[]={"浙A","浙B","浙C","浙D","浙伍弯E","浙F","浙G","浙H","浙J","浙K","浙L"}

String b[]={"杭州","宁波","温州","绍兴","湖州","嘉兴","金华","衢州","台州","丽水","舟山"}

int index = 0

for(int i = 0i<11i++){

if(no.equalsIgnoreCase(a[i])){

index=i

System.out.println("车辆所在地为："+b[i])

}

}

}

}

//不严谨，但是基知御本功能实现了
