The generated hash of theKeyobject is also stored to avoid calculating hash every time during comparisons, to improve the overall performance. 2. Internal Implementation ofHashMap TheHashMapis aHashTablebased implementationof theMapinterface. It internally maintains an array, also called a“bucket ar...
COLLISION OCCURS-Since hashcode() is same, bucket location would be same and collision occurs in hashMap.Since HashMap use a linked list to store in bucket, “Key and Value” object will be stored in next node of linked list. COLLISION RESOLUTION We can find the bucket location by calling...
A collision occurs when a hash function returns same bucket location for two different keys. Since all hash based Map class e.g. HashMap usesequals() and hashCode() contractto find the bucket. HashMap calls the hashCode() method to compute the hash value which is used to find the bucket...
How HashMap works in Java or sometime how get method work in HashMap is common interview questions now days. Almost everybody who worked in Java knows what hashMap is, where to use hashMap or difference between hashtable and HashMap then why this interview question becomes so special? Beca...

return (result % SIZE_OF_MAP); } When employing the hashing function, it is important to take into account the possibility of collisions. This occurs when two keys produce the same output for the function get_hash. In the case of using an array of Maps, a collision resolution technique ...
