getName() After the loop, highest & highestStr will contains your highest key & value from the HashMap. In your loop, just replace the olds variables. You are recreating "highest" variables instead of modifying it. public class NewClass4 l.add(2) l.add(3) l.add(4) l.add(5) ( Collections.max(l)) // 5 Finding the max/min value in an array of primitives using Java.

How to find the Entry with largest Value in a Java Map, How to find the Entry with largest Value in a Java Map. Try this, using standard methods and assuming that the population count is stored as Integers in the HashMap: List list = new ArrayList(zipCodePop.values()) Ĭollections.sort(list, Collections.reverseOrder()) Getting the value should return an Integer with the value of 7. Converting a stream from a hashmap while passing the same comparator used in how to sort a hashmap to the max method will return an java 8 Optional object of type Entry. course, focused on the fundamentals of Spring 5 and Spring Boot 2. ("Top "+n+" entries:") įinding the Highest Value in a Java Map, Take a look at ways to find the maximum value in a Java Map structure. It basically inserts all elements into a PriorityQueue that is sorted according to the values of the map entries. One apporach would be to employ the PriorityQueue that nr4bt already mentioned (I wrote this snippet while he answered). But 33k elements is a number where the O(n*log(n)) complexity of sorting might already have a noticable performance impact. Putting the entries of such a set into a list and sorting it is one option.
