sorting hashmap by key in java 8
Map<String, String> newMapSortedByKey = sample.entrySet().stream()
.sorted((e1,e2) -> e1.getKey().compareTo(e2.getKey()))
.collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue, (e1,e2) -> e1, LinkedHashMap::new));hashmap sort ascending
LinkedHashMap<String, Integer> sortedMap = new LinkedHashMap<>();
unSortedMap.entrySet()
.stream()
.sorted(Map.Entry.comparingByKey())
.forEachOrdered(x -> sortedMap.put(x.getKey(), x.getValue()));Copyright © 2021 Codeinu
