How Eclipse shows the startup interface so fast

Question

Java programs start slowly.

I am programming software for JavaFX. When I double-click the executable jar, it costs about 5 seconds to show the window. I think the JVM spends a little time loading the class.

But when I open Eclipse, the GUI of execution is displayed immediately. How can i do this like eclipse? Does it use other technologies to display a GUI without a JVM?

The eclipse executable is actually a small C program (source code here ).
