Question

我当时是通过在线教程制作游戏的，并且我是slick的初学者，所以我不知道该怎么办才能解决此错误。如果有人可以帮助我，我会很棒。谢谢。

package com.tutorial.main;

import java.util.HashMap;
import java.util.Map;

import org.newdawn.slick.Music;
import org.newdawn.slick.SlickException;
import org.newdawn.slick.Sound;

public class AudioPlayer {

    public static Map<String, Sound> soundMap = new HashMap<String, Sound>();
    public static Map<String, Music> musicMap = new HashMap<String, Music>();

    public static void load() {
        try {
            soundMap.put("Menu_Sound", new Sound("TGame_res/Nikon_Click.ogg"));
        } catch (SlickException e) {
            e.printStackTrace();
        }

        try {
            musicMap.put("Music", new Music("TGame_res/Eletronic_Background.ogg"));
        } catch (SlickException e) {
            e.printStackTrace();
        }
    }

    public static Music getMusic(String key) {
        return musicMap.get(key);
    }

    public static Sound getSound(String key) {
        return soundMap.get(key);
    }
}

如问题所述。

下面是返回的错误。

代码如上所示。This is a photo of the slick libraries imported

将使用AudioPlayer.load（）调用该类；当AudioPlayer.load（）;时，游戏运行完美。已被注释掉。

遵循游戏指南，但使用滑线触及音乐和声音的代码时返回错误
