963 PointsBummer! Expected [pager, phone] from getAvailableContactMethods, but got [(555) 555-5555, (222) 222-2222].
I don't know how else it would want me to return a map with this method
package com.example.model;
import java.util.Map;
import java.util.HashSet;
import java.util.Set;
import java.util.HashMap;
public class Contact {
private String mFirstName;
private String mLastName;
private Map<String, String> mContactMethods;
public Contact(String firstName, String lastName) {
mFirstName = firstName;
mLastName = lastName;
/* This stores contact methods by name
* eg: "phone" => "(555) 555-1234"
*/
mContactMethods = new HashMap<String, String>();
}
public void addContactMethod(String method, String value) {
mContactMethods.put(method,value);
}
/**
* Returns the available contact methods. eg: phone, pager,
*
* @return The name of the contact methods that are available
*/
public Set<String> getAvailableContactMethods() {
// FIXME: This should return the current contact method names.
Set<String> contactMethods = new HashSet <>(mContactMethods.values());
return contactMethods;
}
/**
* Returns the value for the contact method if it exists,
*
* @param methodName The name of the contact method to look up.
* @return The name of the contact methods that are available
*/
public String getContactInfo(String methodName) {
// FIXME: return the value for the passed in *methodName*
return null;
}
public String getFirstName() {
return mFirstName;
}
public String getLastName() {
return mLastName;
}
}

963 PointsThanks, I had completely forgotten about that method.

14,615 PointsYou made a new HashSet with the contact method values. Maps have key-value pairs and they want you to return the keys, not the values. You can use mContactMethods.keySet() to get a set of the keys.
