[英]How do you change a Java Applet into a Screensaver for Windows 8.1?
我一直在尝试为Windows 8.1创建自定义屏幕保护程序。 但是,通过我的研究,我几乎不喜欢这个主题,而且我发现的任何信息已经过时或来自不值得信任的来源。 我已经使用Java大约2年了,但是对于编程而言,我仍然相对较新,也正在使用eclipse作为编译器,请帮忙。 这是我目前拥有的:
import java.applet.Applet;
import java.awt.*;
import java.util.*;
import java.io.*;

该代码还使用2个文本文件“打印”到屏幕
要创建独立的GUI应用程序,请使用java swing或(最新)JavaFX,这样您就可以创建独立的Java应用程序,现在您可以在JVM中使用java命令运行gui应用程序。
为了将Java程序设置为在Windows中作为屏幕保护程序运行-您需要打包Java程序(jar),然后创建某种exe / scr,以便可以设置窗口以使用屏幕保护程序来运行。
