Python Development Techdegree Student 11,470 PointsHey Christian,
In Example.java, the comment "Take the first two elements passed args" is referring to the string of arguments in the
main
method. So what it's asking to take args[0], and args[1] and pass them to thenew User()
constructor. The assumption is that these are the necessary first name and last name arguments that theUser()
constructor needs.In the same file, take a look at the
new FormPost()
constructor call. It looks like it's missing a few necessary arguments as well. Based on the ForumPost constructor signature inForumPost.java
, what do you need to pass to this constructor in order to make it instantiate correctly? You may need to adjust the body of your FormPost constructor to initialize these fields correctly.
Hope that helps!
