推荐答案

该类未作为applet启动，因为它没有扩展JApplet或Applet.

This class is not launching as an applet as it does not extend JApplet or Applet.

即使已解决此问题，小程序客户端中也不会出现任何内容. Applet不调用main方法，而是调用init.另外，不要为applet组件创建新的Frame-将它们添加到applet容器本身.

Even when this is fixed, nothing will appear in the applet client. Applets do not call the main method but rather init. Also don't create a new Frame for applet components - add them to the applet container itself.

使用轻型Swing，而不是使用旧的重量级AWT.还要查看 Java Web Start 进行部署.

Rather than using the old heavyweight AWT, use lightweight Swing. Also look at Java Web Start for deployment.
