Neat way of doing stuff with a List (and such) in Java -

in c# can operations on list, this:

return mylist.average(p => p.getvalue());

this returns average of values. there similar in java? (that save me calculation of sum , division number of elements?)

thanks!

lambdaj provides functionality this:

double totalage = sumfrom(persons).getage(); //divide size average
