Hi there

Question 5, from the self test in Chapter 5 (Kath and Bert�s book) explains that add is not a legal prefix, according to the JavaBeans standard.

Yet on page 10, addMyListener is cited as a legal example.

Why is addSize illegal?

Thank You,

The pattern use here is add...Listener and remove...Listener

"add" is usually used for listeners (for example Swing classes like JComponent use it). It's specified here (6.5 Event Listener Registration): http://java.sun.com/products/javabeans/docs/getListeners.html
