Learn how to sort a LinkedHashMap by values using the Comparable interface in Java with step-by-step examples.
Mapis a common data type when we need to manage key-value associations. TheLinkedHashMapis a popular choice, primarily known for preserving the insertion order. However, in many real-world scenarios, we often need to sort the elements of aLinkedHashMapbased on their values rather than keys....
The simplest way to sort aLinkedHashMapby values is to convert it into a list of key-value pairs. After that, we sort the list based on the values. Then, we create a newLinkedHashMapusing the sorted list. Let’s have a look at an example: ...
privatestaticvoiditerateThroughHashMapJava8(Map<String,Integer>crunchifyMap){ crunchifyMap.forEach((k, v)->{ System.out.println("Key: "+ k +"\t\t\t Value: "+ v); }); } // Let's sort HashMap by Key // Comparable: This interface imposes a total ordering on the objects of each...
Here's an example using the LinkedHashMap class to preserve the order of the entries:Map<String, Integer> sortedMap = new LinkedHashMap<>(); for (Map.Entry<String, Integer> entry : entries) { sortedMap.put(entry.getKey(), entry.getValue()); }...
As discussed above, we useComparator.reverseOrder()to sorting theMapvalues in reverse order. Map<String,Integer>unsortedMap=Map.of("a",1,"c",3,"b",2,"e",5,"d",4);LinkedHashMap<String,Integer>sortedMap=unsortedMap.entrySet().stream().sorted(Map.Entry.comparingByValue(Comparator.reverse...

// toMap() will returns HashMap by default, we need LinkedHashMap to keep the order. Map<String, Integer> result = unsortMap.entrySet().stream() .sorted(Map.Entry.comparingByKey()) .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue, ...
