Which of the following statements is false?

a. In the RGBA color system every color is represented by its red, green and blue color values, each ranging from 0 to 255, where 0 de-notes no color and 255 full color.
b. The alpha value (A of RGBA)—which ranges from 0.0 to 1.0—represents a color’s opacity, with 0.0 being completely transpa-rent and 1.0 completely opaque.
c. JavaFX makes extensive use of properties. A property is defined by creating set and get methods with specific naming conventions.
public void setHour(int hour)
public int getHour()
define a read/write property named hour. Such methods manipulate a corresponding private instance variable that must have the same name as the property.
d. In general, the pair of methods that define a read/write property have the form:
public void setPropertyName(Type propertyName)
public Type getPropertyName()

c. JavaFX makes extensive use of properties. A property is defined by creating set and get methods with specific naming conventions.
public void setHour(int hour)
public int getHour()
define a read/write property named hour. Such methods mani-pulate a corresponding private instance variable that must have the same name as the property.
Actually, typically, such methods manipulate a corresponding private instance variable that has the same name as the property, but this is not required.
