The classes you reference are JavaFX 1.3 classes:

https://docs.oracle.com/cd/E17802_01/javafx/javafx/1.3/docs/api/javafx.animation/javafx.animation.SimpleInterpolator.html

JavaFX 1.3 is deprecated and I don't think binary runtime downloads for it are even available from Oracle anymore.  JavaFX ran a custom language called JavaFX Script, which is not Java.  You should not use it.

JavaFX FAQ

Instead use JavaFX in JDK 8+: https://docs.oracle.com/javase/8/javase-clienttechnologies.htm. 

Delete any imports of classes, such as SimpleInterpolator or CustomNode, that are not part of the JavaFX 8+ API.

Once you have deleted imports you may have other syntax errors in your code where you attempt to use the imported classes, however, you will need to resolve that yourself - there is no simple translation of JavaFX scripts to Java code.
