Stream elements are incorporated into the result by updating it instead of replacing. Stream.collect() works with one argument as collector or three arguments as supplier, accumulator and combiner using lambda expression. Here we will discuss the example of.On this page we will provide java 8 Stream sorted() example. We can sort the stream in natural ordering as well as ordering provided by Comparator. In java 8 Comparator can be instantiated using lambda expression. We can also reverse the natural ordering as well as ordering provided by Comparator.
