为什么 netbeans 中的 Applet 这个词是 Striken？

Question

when I tried to extend Applet in netbeans, the word Applet is striked. I have also imported the required packages. can anybody explain why this is happening and how do i stop this?

Answer 1

Stricken means it is deprecated, and it will probably tell you so if you hover it in your IDE.

Deprecated packages are usually very old and have replacements. They aren't removed immediately from the library because that would break old code. They're not maintained and will be removed with future versions of java. If you're following some sort of tutorial to learn the language, it is likely very old.
