Question: How to implement a bound property in your bean application?Answer: To implement a bound property in the application, follow these steps:► Import the java.beans package. This gives you access to the PropertyChangeSupport class. ► Instantiate a PropertyChangeSupport object. This object maintains the property change listener list and fires property change events. You can also make your class a PropertyChangeSupport subclass. ► Implement methods to maintain the property change listener list. Since a PropertyChangeSupport subclass implements these methods, you merely wrap calls to the property-change support object's methods. ► Modify a property's set method to fire a property change event when the property is changed. |
