正在尝试创建将显示GUI幻灯片的自执行jar文件

Question

我用java写了一个程序，它使用GUI来显示图像和显示引文的幻灯片。我在mac上的终端中使用命令行。我正在尝试创建一个可自执行的jar文件，它将在其所在的任何计算机上运行此程序。我已经和我的CS教授见过很多次了，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文件和jar文件，但是它没有运行。我一直在使用this website作为参考

我看了很多关于它的东西，但问题是我对它了解不多，大多数人都是用hello world这样的简单程序来创建这些东西的。这方面的任何帮助都会非常感谢，因为我在这个程序上花了很多时间，如果我不能在其他计算机上运行它，那么它对我来说几乎是无用的。这些图像位于一个名为Pictures的文件夹中，该文件夹位于eclipse项目的bin文件夹中。

上传图像的代码如下所示

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这样

我不知道你有什么问题，因为你的描述不是很清楚。

您可能将图像作为对本地文件的引用进行传递，而不是将它们添加到Jar文件中。

如果你在你的电脑上有一个游戏的快捷方式，并且你试图将这个快捷方式复制到另一台电脑上，这是完全相同的。这个游戏不会起作用。

您需要将图像添加到您的jar包中。
