Treemap Comparator By Value

A map that further provides a total ordering on its keys. A treemap is not synchronized. Treemap sort by value you can't have the treemapitself sort on the values, since that defies the sortedmapspecification:

A mapthat further provides a total orderingon its keys. A treemap is not synchronized. We can change the natural sorted order behavior, by providing a comparator to the constructor of the treemap.

Class gfg { public static <k, v extends comparable > map<k, v> valuesort (final map<k, v> map) {

Therefore, a more general solution is preferred. Sorting treemap by value in java the elements in treemap are sorted on the basis of keys. Treemap is mutable, meaning we are able to modify the map once it is created. The below code is to sort the treemap by value with the custom comparator logic.
