语法错误，插入"VariableDeclarators"以完成本地变量声明 - Java 选择你的冒险游戏

Question

我需要一些帮助来制作我正在用Java制作的"选择你的冒险"游戏。我有四节课，其中三节写在下面——最后一堂暂时无关紧要。 在Storyline中，keySet()似乎没有注册我有一个Storyline对象，带有一个名为"key"的键。我也很难弄清楚我的Storylines类的范围，如ChooseYourAdventure所示。我得到一个

语法错误，插入"变量声明器"以完成 LocalVariableDeclaration"和"无法解析为 Storylines.s1 的类型"

当我在主函数中调用Storylines.s1时出错。此外，当我在 main 方法之外的 ChooseYourAdventure 类中调用 Storyline 构造函数时，静态 numberOfStories 变量似乎没有递增。任何帮助解决这些问题，非常感谢！

选择你的冒险

public class ChooseYourAdventure {
    private static ChooseYourAdventure cyaGame;
    private static Character player;
    public ChooseYourAdventure()
    {
        ChooseYourAdventure cyaGame = new ChooseYourAdventure();
        Character player = new Character();
    }
    public static void main(String[] args)
    {
//      while(player.checkIsDead() == false)
//      {
//          cyaGame.nextStoryLine();
//      }
        final Storyline s = new Storyline(0, 0, 0, "heyo", "key");
        Storylines.s1;
        System.out.println("key word: " + s.getKeyWord());
        Storyline.printStories();
    }
}

故事 情节

public final class Storylines {
    private static final String text1 = "hey boi";
    public static final Storyline s1 = new Storyline(0, 0, 0, text1, "key");
}

故事 情节

import java.util.HashMap;

public class Storyline {
    public static int numberOfStories = 0;
    public static HashMap<String, Storyline> stories = new HashMap<String, Storyline>();
    private int ageChange;
    private int happinessChange;
    private int meaningChange;
    private String text = "";
    private String keyWord = "";
    public Storyline(int a, int h, int m, String t, String k)
    {
        numberOfStories++;
        stories.put(this.keyWord, this);
        this.ageChange = a;
        this.happinessChange = h;
        this.meaningChange = m;
        this.text = t;
        this.keyWord = k;
    }
    public static void printStories()
    {
        System.out.println("number of Stories: " + numberOfStories);
        System.out.println("Keys:");
        System.out.println("stories.keySet() = " + stories.keySet());
        for(String k : stories.keySet())
        {
            System.out.println(k); // k is not showing up in keySet()?
        }
        System.out.println("Text:");
        for(Storyline s : stories.values())
        {
            System.out.println(s.getText());
        }
    }
    public int getAgeChange()
    {
        return this.ageChange;
    }
    public int getHappinessChange()
    {
        return this.happinessChange;
    }
    public int getMeaningChange()
    {
        return this.meaningChange;
    }
    public String getText()
    {
        return this.text;
    }
    public String getKeyWord()
    {
        return this.keyWord;
    }
}

在您的情况下，StoryLines.s1 期望一些值被初始化，这就是编译器给您错误的原因。比如说，

 public class StaticClass {         
           static int value ;       
           public void show(){      
            System.out.println("Value:: "+value);   
          }
            public static void main(String[] args) {        
              StaticClass.value = 9;        //intialize value
              StaticClass sc = new StaticClass();       
              sc.show();    
        }
      }

同样，您必须在main方法中将值初始化为Storylines.s1。它不会从故事类中初始化的对象中获取值。
