19,302 PointsYour code is almost correct for the constructor. Here is your code:
The field "topic" was already initialized above this. So once inside the constructor don't do: String topic = topic. Instead use "this". Like this:
I just ran this through the challenge and it passed. Sometimes, instead of using "this" a field will be marked "mTopic" instead of "topic." The duplication of terms in Java (such as using "topic" in multiple places) can be a little tricky at first, but you will get used to it.
