![]() Finally, we collect the sorted stream back into a new LinkedHashMap using the collect function.Īs in previous examples, the resulting map is sorted based on the values in ascending order. Then, we sort the stream using the sorted function and provide a comparator based on the values. LinkedHashMap is a Hashtable and linked list-based implementation of Map interface, with predictable insertion order. ![]() We convert the entries of the LinkedHashMap to a stream. You can query the LinkedHashMap with a key, and get the value stored in it. The insertion order is preserved by maintaining a doubly-linked list of all of its entries. (source) Hash table based implementation of the MutableMap interface, which additionally preserves the insertion order of entries during the iteration. Val expectedStudentsSortedByValues = linkedMapOf(ĪssertThat(sortedMap.toList()).containsExactlyElementsOf(expectedStudentsSortedByValues.toList())įirstly, we use the same input as in previous examples. typealias LinkedHashMap HashMap.Letâs have a look at an example: `when given hashLinkedMap then it is sorted by values using list and sortedWith method`() )) Then, we create a new LinkedHashMap using the sorted list. After that, we sort the list based on the values. I will explain you the whole concept of LinkedHashMap by putting 5 key-value pairs in HashMap. Pseudo Code : Integer aKeys LHM.keySet().toArray(new IntegerLHM.size()) // where LHM is name of LinkedHashMap created and aKeys of array to be converted. Printing last and value corresponding to the key. Algorithm: Getting first and value corresponding to the key. The simplest way to sort a LinkedHashMap by values is to convert it into a list of key-value pairs. Method 2: Converting the keys of LinkedHashMap to an integer array.
