Create an array of objects each with word and count properties, then sort it based on the count. #kkjavatutorials #javaabout this video:hello friends,in this video,we will talk and learn about how to write a java program for sort map based on values. The sorted() method takes a comparator as a parameter, making it possible to sort the map by any type of value. Therefore, we can sort the pairs by keeping them in a set and using a comparison logic that compares them with their second field instead of first one.
If you want descending value, simply reverse the comparator Therefore, we can sort the pairs by keeping them in a set and using a comparison logic that compares them with their second field instead of first one. This will let you consume the entries sorted in ascending order of value. Sorting a map by ascending order of value. Finally , either collect it with linkedhashmap or perform the foreachordered operation with linkedhashmap.
