java - 一些扩展小程序的代码

Question

这是我的代码(抱歉放了这个)真的我需要你的帮助你能帮我一下我怎样才能从中删除小程序(init方法)我也不喜欢使用小程序我也是初学者我已经做了一些事情但这并不能解决问题。谢谢

  public class RedGreenGriffin extends Applet {

如果您想在 Swing 中构建独立的 GUI 应用程序，则应该将内容放入 JFrame 而不是 Applet 中。

您还可以使用其他 GUI 框架来构建独立的 Java GUI 应用程序，但 Swing 是最受欢迎的，并且您可能能够在其中找到最有用的文档(包括 Stack Overflow 上的文档) :-) ).
