TreeMap is a Red-Black tree-based implementation of the NavigableMap interface in Java, maintaining key-value pairs in sorted order. Unlike HashMap, TreeMap does not support null keys and has a time complexity of O(log n) for basic operations. It is ideal for scenarios requiring sorted data and efficient range operations, such as event logging, financial applications, scheduling, version control, caching, leaderboards, and spell checking. Key methods include `put`, `get`, `remove`, navigation methods like `firstKey`, `lastKey`, and range views like `headMap`, `tailMap`, and `subMap`.
