Я пишу программу penny pitch на Java, и это карнавальная игра. Призы генерируются случайным образом на доске, и бросается 10 монет. В методе «randSelector», который я написал, я получаю сообщение об ошибке от «prize», потому что в нем говорится, что я не могу вернуть строку в String []. Есть предложения? Это мой код:

 import java.util.Arrays;
import java.util.Random;

public class PennyPitch {

public static void main(String[] args) {
    // TODO Auto-generated method stub
        Random rand = new Random();
        String[][] board = new String[25][25];
        int puzzle = 0;
        int poster = 0;
        int doll = 0;
        int ball = 0;
        int game = 0;
        int misses = 0;
        
        //Create empty board
        Arrays.fill(board, "[        ]");
        
        String[] prizes = {"[ puzzle ]", "[ poster ]", "[  doll  ]", "[  ball  ]", "[  game  ]"};
        for (int i = 0; i < prizes.length; i  ) {
            randSelecter(board, prizes[i], rand);
        }
        //Simulates 10 pennies thrown
        for ( int i = 0; i < 10; i  ) {
            for ( int j = 0; j < 10; j  ){
            int box = rand.nextInt(24);
            if (board[box][j] == "[ puzzle ]"){
                
                puzzle  = 1;
            } else if (board[box][j] == "[ poster ]"){
                poster  = 1;
            } else if (board[box][j] == "[  doll  ]"){
                doll  = 1;
            } else if (board[box][j] == "[  ball  ]"){
                ball  = 1;
            } else if (board[box][j] == "[  game  ]"){
                game  = 1;
            }else {
                misses  = 1;
            }
        }

        System.out.println("Welcome to Penny Pitch!");
        System.out.println("Land on three of a kind and win the prize!");
        System.out.println("You've thrown 10 pennies on the board below,n");

        //Prints 5 x 5 board
        System.out.println(board[0][0]   board[1][1]   board[2][2]   board[3][3]   board[4][4]);
        System.out.println(board[5][5]   board[6][6]   board[7][7]   board[8][8]   board[9][9]);
        System.out.println(board[10][10]   board[11][11]   board[12][12]   board[13][13]   board[14][14]);

        System.out.println("Poster: "   poster );

        System.out.println("Game: "   game );
        System.out.println("Misses: "   misses );
        
        //Checks for a win
        if ( puzzle == 3){
            System.out.println("You won a puzzle!");
        } else if ( poster == 3) {
            System.out.println("You won a poster!");
        } else if ( doll == 3) {
            System.out.println("You won a doll!");
        } else if ( ball == 3) {
            System.out.println("You won a ball!");
        } else if ( game == 3) {
            System.out.println("You won a game!");
        } else {
            System.out.println("Sorry, you lost.");
        }

    }
}
    //Randomly place prizes
    public static String[] randSelecter(String[][] board, String prize, Random rand) {
        for (int i = 0; i < 3; i  ) {
            int pick = rand.nextInt(24);
            int anotherNum = rand.nextInt(24);
            if (board[pick][anotherNum] != "[        ]" amp;amp; board[pick   1][anotherNum 1] == "[        ]"  amp;amp; pick != 24) {
                board[pick   1] = prize;
            } else if (board[pick][anotherNum] != "[        ]" amp;amp; pick != 0 amp;amp; board[pick - 1][anotherNum-1] == "[        ]") {
                board[pick - 1] = prize;
            } else if (board[pick][pick] != "[        ]") {
                for (int k = 0; k < board.length; ) {
                    if (board[k][anotherNum] == "[        ]") {
                        board[k][anotherNum] = prize;
                        break;
                    } else {
                        k  ;
                    }
                }

        for(int x = 0;x<30;x  ) {
            for(int p = 0;p<30;p  ) {
                return board[x][p];
            }
        }
        
    }

}
  

Ваш возвращаемый тип в randSelecter is String[] , но вы возвращаете a String , выполняя return board[x][p] . Измените возвращаемый тип на String :

 public static String randSelecter(String[][] board, String prize, Random rand) {
...
  

или, в качестве альтернативы, измените то, что вы возвращаете
