Как перенести элементы из списков строк, используя события 2 кнопки?

1 голос
/ 09 февраля 2020

Как новичок я хотел бы понять использование событий, создав приложение для перетасовки тайлов. Пожалуйста, помогите мне

Я бы хотел приложение javafx с двумя кнопками:

  • Событие кнопки 1 clickToShuffle(MouseEvent mouseEvent) - щелчок по нему перетасовывает готовый список строк из 136 items (list1: String[] allTiles)
  • Событие кнопки 2 clickToDeal(MouseEvent mouseEvent) - при нажатии на него первые 13 элементов удаляются из списка list1 и переносятся в новый пустой список (list2)

Сведения о результате:

После нажатия кнопки 2 приложение должно удалить первые 13 элементов из списка1. Таким образом, нажатие кнопки 2 означает, что в списке list1 будет 123 элемента. list2 становится списком этих 13 элементов. Не должно быть возможности иметь более 13 элементов в списке 2.

Проблема:

Я бьюсь над кнопкой 2. Я не могу разместить данные " Переменная списка allTiles ", доступная для использования в методе кнопки 2" public void clickToDeal(MouseEvent mouseEvent) "

Вопрос:

После нажатия кнопки 1, как я могу использовать список" allTiles "( в этот момент) и уберите 13 элементов из списка 1, нажав кнопку 2?

Это файл main : 

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

import java.util.Arrays;

public class Main extends Application {

    String[] allTiles = {};

    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("/resources/home.fxml"));

        // create tiles Array
        String[] allTiles = new String[] {"1m1","2m1","3m1","4m1","5m1","6m1","7m1","8m1","9m1","1m2","2m2","3m2","4m2","5m2","6m2","7m2","8m2","9m2","1m3","2m3","3m3","4m3","5m3","6m3","7m3","8m3","9m3","1m4","2m4","3m4","4m4","5m4","6m4","7m4","8m4","9m4","1s1","2s1","3s1","4s1","5s1","6s1","7s1","8s1","9s1","1s2","2s2","3s2","4s2","5s2","6s2","7s2","8s2","9s2","1s3","2s3","3s3","4s3","5s3","6s3","7s3","8s3","9s3","1s4","2s4","3s4","4s4","5s4","6s4","7s4","8s4","9s4","1p1","2p1","3p1","4p1","5p1","6p1","7p1","8p1","9p1","1p2","2p2","3p2","4p2","5p2","6p2","7p2","8p2","9p2","1p3","2p3","3p3","4p3","5p3","6p3","7p3","8p3","9p3","1p4","2p4","3p4","4p4","5p4","6p4","7p4","8p4","9p4","n1","n2","n3","n4","e1","e2","e3","e4","w1","w2","w3","w4","s1","s2","s3","s4","dr1","dr2","dr3","dr4","dg1","dg2","dg3","dg4","dw1","dw2","dw3","dw4"};
        System.out.println(Arrays.toString(allTiles));



        primaryStage.setWidth(1280);
        primaryStage.setHeight(720);
        primaryStage.setTitle("Hello World");
        primaryStage.setScene(new Scene(root, 300, 275));
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

Это контроллер файл:

        // create tiles Array

        System.out.println(Arrays.toString(allTiles));

        // Converting tiles Array to List String
        List<String> list = Arrays.asList(allTiles);
        System.out.println(list);
        System.out.println(allTiles.length);
        System.out.println(list.size());

        // shuffle

        for (int i = 0; i < allTiles.length; i++) {
            int index = (int)(Math.random()*allTiles.length);
            String shuffleTmp = allTiles[i];
            allTiles[i] = allTiles[index];
            allTiles[index] = shuffleTmp;
        }




    }
