Which of the following statements is false?

Question

a. SwingWorker method publish repeatedly sends intermediate results to method process, which displays the results in a GUI component. Method setProgress updates the progress property.
b. Method process executes in the event dispatch thread and receives data from method publish. The passing of values between publish in the worker thread and process in the event dispatch thread is synchronous; process is not necessarily invoked for every call to publish.
c. PropertyChangeListener is an interface from package java.beans that defines a single method, propertyChange.
d. Every time method setProgress is invoked, a PropertyChangeEvent is generated to indicate that the progress property has changed.

Answer 1

b. Method process executes in the event dispatch thread and receives data from method publish. The passing of values between publish in the worker thread and process in the event dispatch thread is synchronous; process is not necessarily invoked for every call to publish. Actually, the passing of values between publish in the worker thread and process in the event dispatch thread is asynchrounous.
