Answer / sheetal sikarwar
hash code is integer value that is return by JVM. when we
compare object by equals() method then this will return
hash code value of object. if this value is same that means
object's memory location is same. that meand object is same.
when we are saving object in HashSet, HashMap and HashTable
then this object will save by Dictonary class. this
Dictonary class is Abstact class that save object with hash
code value.
