如何將Java Applet更改爲Windows 8.1的屏幕保護程序？

Question

我一直在嘗試一段時間來爲Windows 8.1創建自定義屏幕保護程序。然而，通過我的研究，我對這個問題幾乎沒有任何興趣，我發現的任何信息都已經過時，或者來自不值得信任的來源。我已經使用了大約2年的Java，但是對於編程來說我還是比較新的，我也使用eclipse作爲編譯器，請大家幫忙。 這裏是我目前：

import java.applet.Applet; 
    import java.awt.*; 
    import java.util.*; 
    import java.io.*;

而且代碼使用2個文本文件「打印」到屏幕

創建獨立的GUI應用程序，請使用的Java Swing或（最新）的JavaFX，那麼你將能夠創建獨立的Java應用程序，現在您可以在JVM內使用java命令運行gui應用程序。

爲了設置你的Java程序在Windows中作爲屏幕保護程序運行 - 你需要打包java程序（jar）然後創建一些exe/scr，以便你可以設置窗口來使用你的屏保運行。

快速谷歌搜索下面找到鏈接。也許你可以使用與swing相同的過程。
