Sorting a HashMap by its values can be a useful operation in scenarios where you want to retrieve the entries in ascending or descending order based on their values. While HashMap in Java does not maintain an order of elements, you can still sort it based on values. Here’s how you can do it:<\/p>\n

1. Get the entries from the HashMap using entrySet().
\n2. Convert the entries into a List.
\n3. Use the Collections.sort() method to sort the List by values.
\n4. Create a LinkedHashMap to preserve the order of the sorted elements.
\n5. Iterate over the sorted List and put the entries into the LinkedHashMap.
\n6. You now have a sorted HashMap based on values.<\/p>\n
