Courses Plus Student 664 PointsDid not get this part of the code
Please can you help me fix this part of the code, I really don't understand what he is trying to say
return what and how ?
package com.example.model;
import java.util.Map;
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);
// TODO: Add to the contact method map
}
/**
* 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> CurrentContactMethods = mContactMethods.get(method);
return CurrentContactMethods;
}
/**
* 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;
}
}

57,712 PointsHi there,
The hint in the question suggests you want to return a set of the keys within the mContactMethods
map. You can use the method keySet()
to do that. So, return
the result of calling keySet()
on mContactMethods
using dot notation.
Make sense?
Steve.
