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 "
