The java.io.Hashtable class in Java is a data structure that implements the Map interface and stores key-value pairs. It provides a way to store and access data in a tabular form, where each key is unique. The Hashtable class uses a hash function to generate an index for each key, which allows for fast insertion, deletion, and retrieval of key-value pairs. It ensures that keys and values are not null and maintains the insertion order of elements. Hashtable is synchronized and thread-safe, making it suitable for multi-threaded environments. It is commonly used for caching, storing configuration settings, and implementing various algorithms and data structures in Java applications.
