Question

我用几句话创建了一个枚举。我想在gui上显示随机选择一个单词，但是，我不确定如何实际显示随机单词。如果需要更多信息，请随时告诉我，谢谢！

这是枚举：

public enum Words {
    RIFLE,RAILROAD,FARM,SLOPE,LEPERACHAUN,SONG,CREATOR,TENT,FORM,FOOD,DINNER,TICKET,NOVEL,SPARK,
    KITTEN,GUST,SMOKE,HORSE,LOSS,BRAKE,JAZZ,BASEBALL,SIZZLE,LEOPARD,SPARROW,EGG,QUARTER,MULTIPLE,DUPLEX,VOICE,
    GNU,UNDERWEAR,SAND,BED,CANNON,NOTEBOOK,CAUSE,DIRT,PYTHON,SWING,WORD,RAY,SNOW,TRUCK,SILVER,NERVE,DEATH,
    SEASHORE,WATER,COBWEB;

    public String toString() {
        String name = name();
        return name.substring(0, 1) + name.substring(1);
    }

}

以下是我希望显示单词的视图：

import java.awt.Color;
import java.awt.Font;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

import javax.swing.JButton;
import javax.swing.JLabel;

import acm.graphics.GLabel;
import acm.program.Program;

public class HangmanView implements MouseListener, ActionListener {

    private static final int DEFAULT_SIZE = 600;
    private static final Font FONT = new Font("Helvetica", Font.BOLD, 20);
    private JLabel statusMsg;
    private Words words;
    HangmanGraphics Content = new    HangmanGraphics(DEFAULT_SIZE/2,DEFAULT_SIZE/2);
    Hangman game;         // the controller
    HangmanModel model;   // the model

public HangmanView(Hangman game) {

    final GLabel label = new GLabel(words.toString());
    label.setFont(FONT);
    game.add(label, DEFAULT_SIZE/4, DEFAULT_SIZE/4);

}
}

您需要以下代码：

import java.util.Random;

public static void main(String[] args){
    Random random = new Random();
    int rand = random.nextInt(Words.values().length);
    System.out.println(Words.values()[rand]);
}

它的作用是使用Random类创建一个从1到单词数的随机数（rand），然后使用索引rand（Words.values()[rand]）打印出该元素。 Words.values()返回枚举中所有单词的数组。
