In this example, we will sort the values of the map in ascending order using the “comparingByValue()” and the “sort()”. We will first create an integer-type map called “map” as follows: Map<Integer, Integer>map = new HashMap<>(); Then, we put the values to the created map...
You can see that thesorted()method takesComparatoras an argument, making it possible to sort a map with any kind of value. For example, the above sort can be written with theComparatoras: 7 1 publicstaticMap<String,Integer>sortByValue(finalMap<String,Integer>wordCounts) { 2 3 return...
1.Map.Entry.comparingByValue() In Java 8,Map.Entryclass has astaticmethodcomparingByValue()to help sort aMapby values. It returns aComparatorthat comparesMap.Entryin the natural order of values. map.entrySet().stream().sorted(Map.Entry.comparingByValue())... Alternatively, we can pass a c...

To sort a Map<Key, Value> by values in Java, you can create a custom comparator that compares the values and pass it to the sort() method of the Map.Entry class.
