.
Map interface is a unordered collection that allows duplicate elements but not duplicate keys.
It allows null elements but not null keys.

Why doesn't java support multiple inheritance? - CORRECT ANSWERS It supports it, just
through interfaces. It doesn't support multiple inheritance in order to avoid the complexity and
conflicts that result. For example, if more than one superclass has the same base class then the
subclass will receive 2 copies of the same attributes and methods, leading to ambiguity.
Is Javascript case sensitive? - CORRECT ANSWERS Yes
Why are strings immutable? - CORRECT ANSWERS When a string is created and if the string
already exists in the pool, the reference of the existing string will be returned, instead of
creating a new object and returning its reference. If a string is mutable, changing the string with
one reference will lead to the wrong value for the other references.
It would also lead to security issues, since strings are often used in the parameters for database
connections, opening a file, network connections, etc. If strings were mutable those values
could be changed and it would be a security risk.
It would also make hashmaps much less efficient, since they would have to check the hashcode
every time it was used.
