It maintains a configurable concurrency level (default value of 16), which can be specified while creating the map. (The HashMap class is roughly equivalent to Hashtable, except that it is unsynchronized and permits nulls. Maps in Java are initialized in a lot of different ways. ConcurrentHashMap is a subclass of HashMap and is designed to be used in multi-threaded environments. (2pts) In a hash table array of size 5, where the hash function is f (n) no5, if the hash table array is used to store integer keys, will key 3 and key 8 to be put into the same slot in the array If yes, then how to solve this situation 2. This implementation provides all of the optional map operations, and permits null values and the null key. (2pts) Which method of Java HashMap will you use to replace. I am new to java and practicing by creating a simplistic NaiveBayes classifier. Hash table based implementation of the Map interface.
