Java 声音不响

当我尝试播放声音时，会出现错误：

java.lang.NullPointerException
    at sun.applet.AppletAudioClip.<init>(Unknown Source)
    at java.applet.Applet.newAudioClip(Unknown Source)

Exception in thread "Thread-5" java.lang.NullPointerException
    at com.artem.megatale.Sound$1.run(Sound.java:23)

我使用

sound.blockBreak.play（）播放声音
声音存储在res/sound/文件中，并存储在jar文件中。
我尝试更改
blockBreak=新声音（“/sounds/break_stone.wav”）到
blockBreak=新声音（“res/sounds/break_stone.wav”）但我仍然得到错误

有人要我的软件包截图：


有人还说我应该放弃“尝试并捕获”，于是我又犯了一个错误：

我假设
res/sound
存储在Jar中，并且它是
sound
或
sounds
？如果您上传错误日志，或者确保
NullPointerException
在
sound
变量声明中抛出，这可能会有所帮助。此外，包结构的方案或屏幕截图也有助于解决问题。不要过度夸张，删除不必要的try捕获，让实际异常直接发生（虽然您正在打印堆栈跟踪，但仍然会丢失它们）。只需让原始根本原因代码触发异常。然后你将知道确切的原因，你将能够修改和纠正例外的实际原因。我做了你所说的，并更新了问题

Sound.blockBreak.play();
