Basically i have a set of pairs which i want to transform to a map of maps. It seems all you need is to create a map where the key in a employee and the value is the employee 's cars: 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> Note that this will use some unspecified implementations of map and list. Currently, it happens to be hashmap and arraylist, but.
This method accepts following parameters: In this tutorial, we'll take a look at how to convert and collect a stream into a map in java 8 with a pair of mapper functions, a merge function and a supplier function, with practical examples and tips. 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> Map<<strong>employee</strong>, list map = emps.stream().collect(collectors.tomap(function.identity(),employee::getcars);
