8. Alternative collections
  


Doug Lea's collections package page 2 of 3


The collections package from Doug Lea (author of "Concurrent Programming in Java") was first available in October 1995 and last updated in April 1997. It probably offered the first publicly available collections library. While no longer supported, the library shows the complexity added to the class hierarchy when you try to provide updateable and immutable collections, without optional methods in interfaces or wrapper implementations. While a good alternative at the time, its use is no longer recommended. (Doug also helped author some of the Collections Framework.)
