Web the collectors.tomap also accept a supplier function, through which you can specify the particular implementation of map you want to use as your final map. You have collectors.tomap for that purpose : In the above example if you notice the order in which we insert item to the list and the order of the map is not matching right. The first argument is a function that maps the key in the map. Web when mapping collector is used to collect elements of a stream, it first maps/transforms/converts the stream elements of type t to type u using function<t,u>, and then collects them using collector<u,a,r>, in effect allowing your collector which accepts stream to now work with (or adapt to) stream.</p>
