Stuck and I don't know what this challenge wants Java data structure, organizing data, comparable, challenge 3 of 3.

This is in regard to the Java data structure course in the Comparable section and challenge 3 of 3 "Order the blog post's creation date chronologically. There was a previous question but Craig's answer didn't really make alot of sense to me, Here is my compare method:

public int compareTo(Object obj) {
 BlogPost other = (BlogPost) obj;
 if (equals(other)) {
return 0;
}
 return 1; }

I got it, Thank you Craig, You need to compare dates between current and the other with the ".compareTo" method

return mCreationDate.compareTo(other.mCreationDate);

Is comparing date between current and other covered in the video? I can't seem to figure it out.
