Perhaps the collections project could use some of the backlogged code already contributed for it. Fred Loney, as part of JIRA issue COLLECTIONS-183, contributed an AppendableList class. Copy and paste methods to get AppendableXXX decorators, subclass them to get builder classes like the one above, and we'll have a good start. As I said, I'm willing to help. The Goetz article is available at: http://www-128.ibm.com/developerworks/java/library/j-jtp04275.html Respectfully, Eric Jablow
