        words words = new words();
        String easyWords1[] = words.easyWords;

        System.out.println("Welcome to Hangman version 1");
        System.out.println("Please choose a difficulty");
        System.out.println("A: Easy");
        System.out.println("B: Medium");

        char iChoice;

        do {
            selection = scan.nextLine().toUpperCase();
        } while (selection.isEmpty());
        iChoice = selection.charAt(0);
        if (iChoice != 'X') {
            switch (iChoice) {

                case 'A':
                    System.out.println("You have choosen easy:");
                    System.out.println(words.getEasyWords());
                    break;

                case 'B':

                     System.out.println(words.getMediumWords());
                    break;

                    break;
            }
        }
    }
}

词类：

package hangman;

import java.util.Random;


/**

public class words extends Hangman {

      String[] easyWords = {"Bee", "Car", "Fish", "Shed"};
      String[] mediumWords = {"House", "Sheep", "Castle", "Phone"};
      String[] hardWords = {"Octagon", "Crocodile", "Chocolate", "Motorbike"};

    public String[] getEasyWords() {
        return easyWords;
    }

    public void setEasyWords(String[] easyWords) {
        this.easyWords = easyWords;
    }

    public String[] getMediumWords() {
        return mediumWords;
    }

    public void setMediumWords(String[] mediumWords) {
        this.mediumWords = mediumWords;
    }

    public String[] getHardWords() {
        return hardWords;
    }

    public void setHardWords(String[] hardWords) {
        this.hardWords = hardWords;
    }

    @Override
    public String toString() {
        return "words{" + "easyWords=" + easyWords + ", mediumWords=" + mediumWords + ", hardWords=" + hardWords + '}';
    }
}

当我尝试显示每个数组时，我得到的是引用而不是字符串，有人可以帮我吗？

...我得到的是参考而不是字符串...

这就是在 class 中定义方法的方式Object。

由于您无法覆盖数组的该行为，因此您可以遍历它，也可以使用toString( static) 实用程序方法java.util.Arrays。

你看到类似的东西

[Ljava.lang.String;@17bd6a1

这是Object#toString数组的表示String，要显示内容，您可以使用：

Arrays.toString(words.getEasyWords())
