What is the characteristic of TreeMap in Java?

The characteristic of TreeMap in Java that is essential to understand is that it sorts keys in ascending order. TreeMap is part of the Java Collections Framework and is implemented based on a Red-Black tree, which is a type of self-balancing binary search tree. The keys in a TreeMap are naturally ordered based on their natural ordering or by a specified comparator provided at the time of creation of the TreeMap. When keys are added to a TreeMap, they are stored in a way that allows for efficient retrieval, insertion, and deletion, while maintaining the sorted order. This means that when you iterate over the keys of the TreeMap, they will be returned in ascending order, making TreeMap particularly useful for scenarios where you need to maintain a sorted collection of keys. Understanding this characteristic helps in scenarios where ordered data structures are required and assists in leveraging TreeMap effectively in your applications.
