I have been working on a small applet/game over the past week and someone recommended that I make it into a JAR file. 在过去的一周中，我一直在开发一个小型applet /游戏，有人建议我将其制作为JAR文件。 After looking into this more on Google I found a tutorial and started to follow it. 在Google上研究了更多内容之后，我找到了一个教程并开始关注它。 However, I soon realized that I needed to choose a class file that had a main method in it. 但是，我很快意识到我需要选择一个包含主要方法的类文件。 Applets do not use a main so I was wondering how I could still make it into a JAR file. Applet不使用主程序，因此我想知道如何将其转换为JAR文件。 Thanks! 谢谢！

Yes they sure can. 是的，他们肯定可以。 In fact to have a good chance of being launched at all, applets need to be digitally signed, which can only be done with classes in a Jar. 实际上，要完全有机会启动小程序，必须对小程序进行数字签名，这只能通过Jar中的类来完成。

That sounds like a problem with your IDE (you don't yet know how to use it, as opposed to having it use you). 这听起来像是您的IDE的问题（相对于让您使用它，您还不知道如何使用它）。

BTW: BTW：

Why code an applet? 为什么要编写小程序？ If it is due to the teacher specifying it, please refer them to Why CS teachers should stop teaching Java applets . 如果是由于老师指定了原因，请向他们介绍为什么CS老师应该停止教Java小程序。
Better to convert the applet to a desktop app., add a main(String[]) method (jar it and sign it) and launch it from a link on a web page using Java Web Start . 最好将applet转换为桌面应用程序。添加一个main(String[])方法（将其添加并签名），然后使用Java Web Start从网页上的链接启动它。
