Question

我试图将RestaurantSelector1类拉入CuisineChoice，以便我能够让用户输入选择，然后我可以将其分配给RestaurantSelector1中的变量（如果这有意义的话。这就是我所拥有的：< / p>

在RestaurantSelector1：

public class RestaurantSelector1 {

public static String getRandom(List<String[]> list) {
Random random = new Random();
int listAccess = random.nextInt(list.size());
String[] s = list.get(listAccess);
return s[random.nextInt(s.length)];


}


public static void main(String[] args){
ArrayList<String[]> WestVillageCuisine = new ArrayList<String[]>();
WestVillageCuisine.add(Expensive.WestVillage.italian);
.
.
.
WestVillageCuisine.add(Expensive.WestVillage.greek);

final String[] randomCuisine =      WestVillageCuisine.get(random.nextInt(WestVillageCuisine.size()));
final String randomRestaurant =  randomCuisine[random.nextInt(randomCuisine.length)];
final String[] randomWVItalian = WestVillageCuisine.get(0);
final String westVillageItalian = r    randomWVItalian[random.nextInt(randomWVItalian.length)];
System.out.println(getRandom(WestVillageCuisine));
System.out.println(randomRestaurant);
System.out.println(westVillageItalian);
}

这是烹饪选择课：

class CuisineChoice{
public static void main(String[] args){
RestaurantSelector1 A = new RestaurantSelector1();

System.out.println("What price range are you looking for? one = $-$$ and two = $$$-$$$$");
    Scanner scan2 = new Scanner(System.in);
    String price = scan2.next();
    if (price.equals("two")){
        price = "Expensive";
    System.out.println("In which neighborhood would you like to eat?");
    Scanner scan = new Scanner(System.in);
    String location = scan.next();
if (null != location)switch (location) {
        case "Tribeca":{
            System.out.println("Great! And what type cuisine would you like in " + location + " ?");
            Scanner scan1 = new Scanner(System.in);
            String type = scan1.next();
            System.out.print(location + " " + type + " " + price);


            break;

            }
        case "West Village":{
            System.out.println("Great! And what type cuisine would you like in " + location + " ?");
            Scanner scan1 = new Scanner(System.in);
            String type = scan1.next();
            System.out.print(location + " " + type + " " + price);

                break;
            }
        case "Flatiron":{
            System.out.println("Great! And what type cuisine would you like in " + location + " ?");
            Scanner scan1 = new Scanner(System.in);
            String type = scan1.next();
            System.out.print(location + " " + type + " " + price);
                break;
            }
        case "Chelsea":{
            System.out.println("Great! And what type cuisine would you like in " + location + " ?");
            Scanner scan1 = new Scanner(System.in);
            String type = scan1.next();
            System.out.print(location + " " + type + " " + price);
                break;
            }
        default:
            break;
    }
    }  
    else{
    price= "Inexpensive"; System.out.println("In which neighborhood would you like to eat?");
    Scanner scan3 = new Scanner(System.in);
   String location1 = scan3.next();
if (null != location1)switch (location1) {
        case "Tribeca":{
            System.out.println("Great! And what type cuisine would you like in " + location1 + " ?");
            Scanner scan1 = new Scanner(System.in);
            String type = scan1.next();
            System.out.print(location1 + " " + type + " " + price);
                break;
            }
        case "West Village":{
            System.out.println("Great! And what type cuisine would you like in " + location1 + " ?");
            Scanner scan1 = new Scanner(System.in);
            String type = scan1.next();
            System.out.print(location1 + " " + type + " " + price);
                break;
            }
        case "Flatiron":{
            System.out.println("Great! And what type cuisine would you like in " + location1 + " ?");
            Scanner scan1 = new Scanner(System.in);
            String type = scan1.next();
            System.out.print(location1 + " " + type + " " + price);
                break;
            }
        case "Chelsea":{
            System.out.println("Great! And what type cuisine would you like in " + location1 + " ?");
            Scanner scan1 = new Scanner(System.in);
            String type = scan1.next();
            System.out.print(location1 + " " + type + " " + price);
                break;
            }
        default:
            break;
    }

}
}
}

我无法弄清楚如何使用位置和美食类型的用户输入作为输入，以获得该位置的随机餐厅。我甚至无法让RestaurantSelector1课程出现在CuisineChoice中。

非常感谢任何帮助！

两者都有main方法，哪一个是应用程序的起点，你的应用程序的结构是什么，它们是在同一个包中还是在不同的包中？并且你在if语句等代码中有一些拼写错误，它没有＆＃34; {＆＃34;打开陈述，在案件陈述中你不需要＆＃34; {}＆＃34;。

if (null != location)switch (location) {

应该是：

if (null != location){ switch (location) {

从同一个包调用一个类并分配变量
