[英]How do you change a Java Applet into a Screensaver for Windows 8.1?
我一直在嘗試為Windows 8.1創建自定義屏幕保護程序。 但是,通過我的研究,我幾乎不喜歡這個主題,而且我發現的任何信息已經過時或來自不值得信任的來源。 我已經使用Java大約2年了,但是對於編程而言,我仍然相對較新,也正在使用eclipse作為編譯器,請幫忙。 這是我目前擁有的:
import java.applet.Applet;
import java.awt.*;
import java.util.*;

該代碼還使用2個文本文件“打印”到屏幕
要創建獨立的GUI應用程序,請使用java swing或(最新)JavaFX,這樣您就可以創建獨立的Java應用程序,現在您可以在JVM中使用java命令運行gui應用程序。
為了將Java程序設置為在Windows中作為屏幕保護程序運行-您需要打包Java程序(jar),然后創建某種exe / scr,以便可以設置窗口以使用屏幕保護程序來運行。
