Is it possible to return more than one value from a method in Java? [duplicate]

Answer 1

You can following ways to do this:

1. Use a Container class, for example

   public class GameStatusAndRolls {
       String gameStatus;
       String rolls;
       ... // constructor and getter/setter
   }
   public static GameStatusAndRolls crapsGame(String gameStatus, String rolls) {
       return new GameStatusAndRolls(gameStatus, rolls); 
   }
   public static void main(String[] args) {
       ...
       GameStatusAndRolls gameStatusAndRolls = crapsGame(gameStatus, rolls);
       gameStatusAndRolls.getGameStatus();
   

2. Use List or an array, for example

   public static List crapsGame(String gameStatus, String rolls) {          
       return Arrays.asList(gameStatus, rolls); 
   }
   private static final int GAME_STATUS = 0;
   private static final int ROOLS = 0;
   public static void main(String[] args) {
       ...
       List list = crapsGame(gameStatus, rolls);
       ... list.get(0)...list.get(GAME_STATUS);
       ... list.get(1)...list.get(ROOLS);
   

   or

   public static String[] crapsGame(String gameStatus, String rolls) {          
       return new String[] {gameStatus, rolls}; 
   }
   private static final int GAME_STATUS = 0;
   private static final int ROOLS = 0;
   public static void main(String[] args) {
       ...
       String[] array = crapsGame(gameStatus, rolls);
       ... array[0]...array[GAME_STATUS];
       ... array[1]...array[ROOLS];
   

3. Use Map, for example

   public static Map crapsGame(String gameStatus, String rolls) {  
       Map result = new HashMap<>(2);
       result.put("gameStatus", gameStatus);           
       result.put("rolls", rolls);
       return result; 
   }
   public static void main(String[] args) {
       ...
       Map map = crapsGame(gameStatus, rolls);
       ... map.get("gameStatus")...map.get("rolls");
