我在java中编写了一个使用GUI的程序，显示图像和显示引号的幻灯片。我在mac上使用终端中的命令行。我正在尝试创建一个自我执行的jar文件，它将在任何计算机上运行该程序。我遇到了我的CS教授很多时间，但他遇到的问题是加载包含jar文件中所有图片的文件夹。我们已经创建了manifest.mf文件，我们已经创建了jar文件但它没有运行。我一直在使用this website作为参考
我已经看了很多这方面的问题，但问题是我对此并不了解，大多数人用hello world这样的简单程序创建这些东西。任何有关这方面的帮助都将非常感激，因为我花了很多时间在这个程序上，如果我不能在其他计算机上运行它，那对我来说几乎没用。这些图像位于名为Pictures的文件夹中，该文件夹位于eclipse项目的bin文件夹中。
我上传图片的代码如下所示
for(int i = 0; i < pic.length-1; i++)
{
pic[i] = new ImageIcon(this.getClass().getResource("/Pictures/" + i +".JPG")); // Fills array with pictures
}
我的其余代码看起来像

我不确定你的问题是什么，因为你的描述不是很清楚。
可能您将图像作为对本地文件的引用传递，而不是将它们添加到Jar文件中。
如果您的PC中有游戏的快捷方式，并且您尝试将该快捷方式复制到另一台计算机，则完全相同。游戏不起作用。
您需要将图像添加到jar包中。
