Question

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.

Answer 1

The question is incomplete.

The complete question is:

Which of the following statements is false?

a.) 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.

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 transparent and 1.0 completely opaque.

c.) 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 denotes no color and 255 full color.

d.) In general, the pair of methods that define a read/write property have the form:

public void setPropertyName(Type propertyName)

public Type getPropertyName()

Answer:

a.) 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.

Explanation:

JavaFX is a software platform for creating and delivering desktop applications, including rich Internet applications (RIAs) that can run across a large variety of devices. JavaFX is intended to replace Swing as the standard GUI library for Java SE, but both will be included for the nearest future. It is a framework built on a Java core for visual effect programming. JavaFX is a set of graphics and media packages that enables developers to design, create, test, debug, and deploy rich client applications that usually operate consistently across diverse platforms.

The alpha value (A of RGBA)-which spreads from 0.0 to 1.0-represents a color's opacity, with 0.0 being completely transparent and 1.0 completely opaque. 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 denotes no color and 255 full color and in general, the pair of methods that define a read/write property have the form:

public void setPropertyName(Type propertyName)

public Type getPropertyName().
