Sorting for Key-Value Pairs in a TreeMap
We must provide a custom Comparator during TreeMap instantiation to create a custom order for key-value pairs in a TreeMap. The items’ storage order will be specified by this comparator.
How to Implement a Custom Order or Sorting for Key-Value Pairs in a TreeMap in Java?
The Java Collections Framework includes the TreeMap class, in which Java offers a sorted collection of key-value pairs. By default, TreeMap uses a custom Comparator or arranges components according to their natural ordering. In this article, we will learn how to apply a custom order for key-value pairs in a TreeMap.
