Java SplashScreen 是如何工作的？
How Java SplashScreen works?
我需要在 java 中实现 SplashScreen，我目前正在向 How to Create a Splash Screen 学习，但是有一段说
Fortunately, Java™ SE 6 provides a solution that allows the application to
display the splash screen much earlier, even before the virtual machine starts.
A Java application launcher is able to decode an image and display it in a
simple non-decorated window.
如果 SplashScreen 是 java class，即使虚拟机启动，java 运行 SplashScreen 怎么可能？
如果您在 jar MANIFEST 文件中定义启动画面，它会在 Java VM 启动之前加载并使用本机代码显示。在这种情况下无需加载 class。稍后，您可以获取 SplashScreen 实例来编辑 and/or 关闭它。

或命令行选项：

Java Platform, Standard Edition (Java SE, formerly known as J2SE)
version 6, provides a solution that allows the application to show the
splash screen much earlier, even before the virtual machine starts.
Now, a Java application launcher is able to decode an image and
display it in a simple nondecorated window.
