A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program should output the phone number associated with that name. Assume that the list will always contain less than 20 word pairs. Ex: If the input is: 3 Joe, 123-5432 Linda,983-4123 Frank, 867-5309 Frank

Map

A map is defined as the name of a higher-order function in most of the programming languages that applies a given function to each element of a functor, such as a list, and returns a list of results in the same order. A map is also called the collection of values based on a key, i.e. a key and value pair. A map has its own set of keys. Duplicate keys are not permitted in the Map, although duplicate values are permitted. Because a Map cannot be navigated, it must be converted to a Set using the keySet() or entrySet() methods. For key-value association mapping, such as dictionaries, maps are ideal.

7.7 LAB: Contact list
A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address,
birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs
consist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program should
output the phone number associated with that name. Assume that the list will always contain less than 20 word pairs.
Ex: If the input is:
3 Joe, 123-5432 Linda,983-4123 Frank, 867-5309 Frank
the output is:
867-5309
Your program must define and call the following method. The return value of getPhoneNumber() is the phone number associated with the
specific contact name.
public static String getPhoneNumber (String [] nameArr, String [] phoneNumberArr, String contactName, int arraySize)
Hint: Use two arrays: One for the string names, and the other for the string phone numbers.
