Bound Properties. A bound property notifies listeners when its value changes. This has two implications: The bean class includes addPropertyChangeListener() and removePropertyChangeListener() methods for managing the bean's listeners. When a bound property is changed, the bean sends a PropertyChangeEvent to its registered listeners.
SwingWorker supports bound properties, which are useful for communicating with other threads. Two bound properties are predefined: progress and state. As with all bound properties, progress and state can be used to trigger event-handling tasks on the event dispatch thread.

This mechanism is often used in graphical user interfaces (GUIs) to synchronize the state of components like buttons, text fields, or sliders. When a property is marked as “bound,” it means that the JavaBean will fire events when ...
Bounded Type Parameters. There may be times when you want to restrict the types that can be used as type arguments in a parameterized type. For example, a method that operates on numbers might only want to accept instances of Number or its subclasses. This is what bounded type parameters are for.
