A DESCRIPTION OF THE REQUEST :
Creating new instances of generic collections can be very verbose.
e.g.
Map<Integer, FindMatchResults> resultsMap = new HashMap<Integer, FindMatchResults>();

Create factory methods in the various Collections subclasses that use capture to reduce the amount of typing, so I can go:

Map<Integer, FindMatchResults> resultsMap = HashMap.create();


JUSTIFICATION :
Simpler code is easier to read, write and debug.
Construction of new generic collections classes is extremely common, and the verbosity makes code harder to work with.
