Is verification algorithm broke again?

Question about the task

Resolved

My satisfied all requirements, but still didn't pass verification.

1. Enter a few strings (keys) from the keyboard [in a loop].
The following strings (keys) are allowed: "user", "loser", "coder", "programmer".
Stop reading in strings after reading in any string that does not match one of the above.

2. For each entered string:
2.1. Create the appropriate object [see Person.java], e.g. create a User object for the string "user".
2.2. Pass this object to the doWork method.

3. Write an implementation of the doWork method, which:
3.1. Calls the live() method on the passed object if person is a User.
3.2. Calls the doNothing() method if person is a Loser.
3.3. Calls the writeCode() method if person is a Coder.
3.4. Calls the enjoy() method if person is a Programmer.

Requirements:

The main method must read strings from the keyboard.
The main method should stop reading strings from the keyboard as soon as the entered string does not match one of the allowed strings ("user", "loser", "coder", "programmer").
For each correctly entered string ("user", "loser", "coder", "programmer"), call the doWork method with the appropriate Person object as the argument.
The Solution class must implement a doWork method with one Person parameter.
The doWork method should call the live() method on the passed object if it is a User.
The doWork method should call the doNothing() method on the passed object if it is a Loser.
The doWork method should call the writeCode() method on the passed object if it is a Coder.
The doWork method should call the enjoy() method on the passed object if it is a Programmer.

package com.codegym.task.task14.task1411; import java.io.BufferedReader; import java.io.InputStreamReader; /* User, loser, coder and programmer */ public class Solution { public static void main(String[] args) throws Exception { Person person = null; String key = null; // Here's the loop for reading the keys. Item 1 try(BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); ) { switch (reader.readLine()){ case "user": person = new Person.User(); break; case "loser": person = new Person.Loser(); break; case "coder": person = new Person.Coder(); break; case "programmer": person = new Person.Programmer(); break; default: return; } doWork(person); } } public static void doWork(Person person) { switch (person.getClass().getSimpleName()){ case "User": ((Person.User)person).live(); break; case "Loser": ((Person.Loser)person).doNothing(); break; case "Coder": ((Person.Coder)person).writeCode(); break; case "Programmer": ((Person.Programmer)person).enjoy(); break; default: return; } } }

solution

Where is the loop? The note on line16 says that there is a loop, but no loop exists in the code.
