The TODO
comments show you what to do where, as prompted by the question in the challenge.
So, the first stage says: Add a constructor that accepts a String named topic to Forum.java. Initialize the private field topic in the constructor to the value passed in. There's two stages here; let's separate them. First is Add a constructor that accepts a String
named topic
to Forum.java
.
We know that a constructor is a method that is named the same as the class. It has no returned data type but will accept incoming parameters - in this case a String
named topic
. The constructor is public. So, add a public
method, inside Forum.java
, which returns no data type (it doesn't even return void
) that accepts a String
called topic
. Let's just do that first - don't worry about what's inside the constructor for now ... we'll do that in a bit...
With me?
Steve.
