Question

How do we describe the situation in which two or more elements in a hash map have equal hashcodes? There is a race condition There is a collision The map is corrupted There are equal elements Suppose list 1 is ["Atlanta", "Macon"] and list 2 is ["Atlanta", "Macon", "Savannah"], which of the following returns true? list1.contains(list2) list2.contains(list1) list1, contains(list2.get(2)) list2.contains(list1 .get(0)) Closing an Output Stream ensures that the data in the buffer are sent to the destination. true false

Explanation / Answer

ANSWERS:

23. They are Equal Elements

No duplicacy is allowed in has sets. Two or more same elements in the hashmap can have same hashcodes.

24. list2.contains(list1)

All the elements of list 1 are present in list 2. Hence, it will return true.

List 2 has "Atlanta" and "Macon" from list 1 and an extra element "Savannah" which is contained in list 2 only.

25. True

Closing an Output stream will ensure that all the data in the buffer has reached its destination.
