同じパッケージからのクラスの呼び出しと変数の割り当て

Question

RestaurantSelector1クラスをCuisineChoiceにプルして、ユーザーがRestaurantSelector1の変数に割り当てることのできる選択肢を入力できるようにしています。これは私が持っているものです。RestaurantSelector1で

：

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); 
} 

そして、これは料理Choiceクラスです：

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; 
    } 

} 
} 
} 

私がどれだけトンを把握することはできませんo場所と料理タイプのユーザー入力を入力として使用して、その場所にあるその料理のランダムレストランを取得します。私はCuisineChoiceにRestaurantSelector1クラスを表示することさえ問題になっています。

ご協力いただければ幸いです。

どちらもアプリケーションの開始点であるメインメソッドと、アプリケーションの構造体は同じパッケージまたは異なるパッケージにありますか？ if文のようなコードでいくつかのタイプミスがありますが、 "{"は文を開きません。case文では "{}"は必要ありません。

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

それは次のようになります。

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