java.util.Pair

[assembling signals]

Hi!

Do you mean, it would be good to have a "standard" implementing class of the interface Map.Entry<K,V> ?
This does exist: AbstractMap.SimpleEntry<K,V>. Well, of course both the interface and the class are
somewhat 'hidden', but nevertheless, they do exist.

Simply an immutable and Serializable class, two final fields, one constructor, two getters (?), and no static factory methods. (S)he who does the real implementation has the privilege to choose between head/tail and car/cdr.
