Sort map by value using lambdas and streams

by

You can always start reading the documentation and some tutorials.

map.entrySet().stream()
        .sorted(Map.Entry.<String, Integer>comparingByValue().reversed()) 
        .limit(10) 
        .forEach(System.out::println); // or any other terminal method
