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;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
// initialize Scanner class
Scanner sc = new Scanner(System.in);
// initialize Hashtable
// tells java that both key and value will be of type String
Hashtable 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(",");
// get the name
String name = details[0];
// get the code
String code = details[1];
// put the record in the dictionary
// here name is key and code is value corresponding to it
my_dict.put(name, code);
}
// get the name
// 3rd part of the input
String name = sc.next();
// get the code corresponding to name in the dictionary
String code = my_dict.get(name);
// print the code
System.out.println(code);
}
}"
I try to run it, but I keep getting "
LabProgram.java:4: error: class Main is public, should be declared in a file named Main.java public class Main { ^ 1 error"

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. 338758.2149958.qx3zqy7 LAB 6.39.1: LAB: Contact list 0/10 АCTIVITY 2:58 PM O Type here to search (1 10/22/2021 ..
