The program above declares the variable hm to be public, so that the variable could be read by other programs.

However, for data encapsulation, we do not want the content of the map to be modified, other than by methods in the class. It is argued that since hm is declared as final, it should be safe.

Explain why it is not safe and implement approach to correct it.

Non-compliant code example public class myClass \{ public static final HashMap hm = new HashMap(); I/TODO: constructor which take a map as input I/TODO: method for querying the map given an integer key I/TODO: method for adding a pair into the map \}
