Create a class Map Tester (either in your current project or in a new project). In it, use a Hash Map to implement a phone book similar to the one in the example above. (Remember that you must import java.util.Hash Map.) In this class, implement two methods: public void enter Number(String name, String number) and public String lookup Number(String name) The methods should use the put and get methods of the Hash Map class to implement their functionality.
