JavaFX Lighting Effect

This effect is used to lighten a node from a light source. There are various kinds of light sources i.e. Point, Distant and Spot. The class javafx.scene.effect.Lighting represents the lighting effect. We need to instantiate this class in order to generate an appropriate effect on the node.

contentInput	It is a Effect object type property. It represents the content input for the Effect.	setContentInput(Effect value)
diffuseConstant	It is a Double type property. It represents the diffuse constant.	setDiffuseConstant(Double value)
