JavaFX not available, what now?

Question

I have a JavaFX application, but when people try to run it nothing happens because they got no JavaFX on their system, because they are using OpenJDK for example.

What can I do to inform people about the problem?

Best way would be to have an Alert informing the user about that, is there a way to do this with basic Java functionality?

Answer 1

您可以使用Swing应用程序启动并检查Java FX是否可用，如下所示：

private static boolean isJavaFxAvalaible() {
        try {

            ClassLoader.getSystemClassLoader().loadClass("javafx.application.Application");

            return true;
        } catch (ClassNotFoundException e) {
            return false;
        }
    }

如果是这样，只需加载您的Main JavaFX，这是一个示例：

Launch JavaFX application from another class

希望这可以为您提供帮助。
