JavaFX | Stop Class

Stop class is a part of JavaFX. Stop class contains an offset and an color. Defines one element of the ramp of colors to use on a gradient. Stop class inherits Object class

Constructor of the class:

• Stop(double o, Color c): Create a new Stop object with specified offset and color.

Commonly Used Methods:

Method	Explanation
equals(Object o)	Returns whether two Stop objects are equal or not.
getColor()	Returns the color gradient at this offset.
getOffset()	Returns the offset of the Stop.
hashCode()	Returns the hashcode of the Stop object.

Java program to create stops add it to linear gradient and apply it to the circle: In this program we will create an array of Stop objects with their offset values ranging from 0 to 1. Create a LinearGradient object with specified stops. Then create a circle with specified x, y positions, and radius and add the linear gradient to it. Create a VBox and set the alignment of it. Add the circle to the vbox and add the vbox to the scene and add the scene to the stage and call the show() function to display the results.
