Chapter 7, Problem 2P

The following code creates a small phone book. An array is used to store a list of names and another array is used to store the phone numbers that go with each name. For example, Michael Myers phone number is 333-8000 and Ash Williams’ phone number is 333-2325.

Write the method lookupName so the code properly looks up and returns the phone number for the input target name. lookupName should return a blank string if the name is not in the phone book.

Scanner kbd = new Scanner (System.in);

String[] name = (“Michael Myers”, “Ash Williams”, “Jack Torrance”, “Freddy Krueger”);

String [] phoneNumbers = (“333-8000”, “333-2323”, “333-6150”, “339-7970”):

System.out. print ln (“Enter name to look up.”);

String targetName = kbd.nextLine();

String targetPhone = lookupName (targetName, names, phoneNumbers);

System.out.println (“The phone number is” + targetPhone);

Program Project 13 asks you to rewrite this program using an array of a single object. The object-based approach is scalable than this approach, which requires a separate array to be managed for every property of the phone contact.
