Enums provide a set of named constants.
All three are used for abstraction and modularity in Java.
Abstract classes and interfaces are used for polym...

I applied via Naukri.com and was interviewed before Mar 2020. There were 4 interview rounds.
Hashtable is synchronized while hashmap is not.
Hashtable is thread-safe while hashmap is not.
Hashtable does not allow null keys or values while hashmap allows one null key and multiple null values.
Hashtable is slower than hashmap due to synchronization.
Hashtable is a legacy class while hashmap is a newer implementation.
Hashmap is not thread-safe while Concurrent Hashmap is thread-safe.
Hashmap is not suitable for multi-threaded environments as it can lead to race conditions and data inconsistencies.
Concurrent Hashmap allows multiple threads to access and modify the map concurrently without any data inconsistencies.
Concurrent Hashmap uses a technique called lock striping to achieve thread-safety.
Concurrent Hashmap is slower than Hashma...
