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.)
