Question

首先，我会说我的Jframe打开并保持打开状态10秒钟。我为孩子们写了一些游戏，向他们展示编程的未来或计算机科学......无论如何

无论谁获胜我都有另一个Jframe设计用于弹出，我希望播放一个声音片段。目前声音片段在源文件夹中，我有一点方法来播放它，但它不起作用。这是代码

Answer 1

我认为问题在这里clipOpen("applause3.wav")。尝试使用/applause3.wav。你的wav文件在哪里？例如，它适用于我的路径"/res/1.mp3"，1.mp3文件存在于文件夹res的{{1}}文件夹中。

编辑：替换您的代码并观看异常，它不在src方法中：

clipStart

尝试在jframe打开时获得掌声
