Word pairsconsist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program shouldoutput 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 Frankthe output is:867-5309Your program must define and call the following method. The return value of getPhoneNumber() is the phone number associated with thespecific contact name.public static String getPhoneNumber(String[] nameArr, String[] phoneNumberArr, String contactName, intarraySize)Hint: Use two arrays: One for the string names, and the other for the string phone numbers.338758.2149958.qx3zqy7LAB6.39.1: LAB: Contact list0/10АCTIVITY2:58 PMO Type here to search(110/22/2021..

I need to write a program which allows me to input "3 Joe,123-5432 Linda,983-4123 Frank,867-5309 Frank" and output "867-5309". This is the code I have so far..."

import java.util.Hashtable;

// initialize Scanner class
Scanner sc = new Scanner(System.in);
// initialize Hashtable
// <String, String> tells java that both key and value will be of type String
Hashtable<String, String> my_dict = new Hashtable<>();

// get the count of records to be entered
// 1st part of the input
int n = sc.nextInt();

// execute for loop n times
// 2nd part of the input
for (int i = 0; i < n; i++) {
// get a record from the user. example: Linda,983-4123
String s = sc.next();
// split the string on comma to get the name and code in an array
String[] details = s.split(",");

String name = details[0];
// get the code
String code = details[1];

// put the record in the dictionary
