How is Hashmap in Java implemented internally? What are the pros and cons to use it? What are the complexities it provides for insert, delete and lookup?
Are there any other data structures in Java that can be used as an alternative to Hashmap?
Yes, Java provides many other data structures that can be used as an alternative to Hashmap, such as TreeMap, LinkedHashMap, ConcurrentHashMap, and Hashtable. These data structures provide different tradeoffs in terms of performance, memory usage, and concurrency handling.
