It looks like you are on Task 1, which states:
In this first step, modify the
addContactMethod
method to store the information in themContactMethods
Map.
Let's start with a hint and see if it helps. What we need to do here is to put
the info passed into the addContactMethod()
into our map, mContactMethods
. I seem to recall a video from Exploring the Java Collection Framework module on maps and put
ting and get
ting data, if you are still stuck you might review that video.
Post back if you are still stuck.
Happy coding,
Ken
