We passed the Comparator to sort the Map by Key Object’snameproperty in ascending order. Let’s see the result:- Map<ComplexKey,String>sortedTreeMap=newTreeMap<>(Comparator.comparing(ComplexKey::getName));sortedTreeMap.putAll(map);System.out.println(sortedTreeMap);// {ComplexKey(name=key...
Let’s implement our solution in Java usingPriorityQueues: class MedianOfIntegerStream { private Queue<Integer> minHeap, maxHeap; MedianOfIntegerStream() { minHeap = new PriorityQueue<>(); maxHeap = new PriorityQueue<>(Comparator.reverseOrder()); } void add(int num) { if (minHeap.size()...
We can sort the Map by key using streams with built-in comparatorMap.Entry.comparingByKey() Sort the Map bykey in alphabeticalorder and print it:- users.stream().collect(Collectors.toMap(User::getName,User::getAge,(o1,o2)->o1)).entrySet().stream().sorted(Map.Entry.comparingByKey())...
