a) Hashing: When you insert a key-value pair, the HashMap applies the hashCode() method on the key to generate a hash value. This hash value is then used to determine the index of the corresponding bucket in the underlying array.b) Handling Collisions: In some cases, different keys can...
In Java, a Multimap is a data structure that maps keys to multiple values. Unlike traditional Java maps, which map each key to a single value, a Multimap allows one key to be associated with multiple values. This can be useful for situations where you need to represent a one-to-many ma...

Table should be in 2NF Transitive functional dependency of non-prime attribute on any really key ought to be eliminated. An attribute that isn't important for any candidate key is known as non-prime attribute. As such 3NF can be made sense of this way: A table is in 3NF in the event...
Depending on the security level set in the Java Control Panel, RIAs that have an expired certificate might not be allowed to run. However, if the signature is time stamped and the time stamp shows that the certificate was valid when the RIA was signed, the RIA is allowed to run....
