I'm not sure what wrong now
package com.example;
import java.util.Date;
public class BlogPost implements Comparable {
private String mAuthor;
private String mTitle;
private String mBody;
private String mCategory;
private Date mCreationDate;
public BlogPost(String author, String title, String body, String category, Date creationDate) {
mAuthor = author;
mTitle = title;
mBody = body;
mCategory = category;
mCreationDate = creationDate;
}
public String[] getWords() {
return mBody.split("\\s+");
}
public String getAuthor() {
return mAuthor;
}
public String getTitle() {
return mTitle;
}
public String getBody() {
return mBody;
}
public String getCategory() {
return mCategory;
}
public Date getCreationDate() {
return mCreationDate;
}
public int compareTo(Object obj) {
BlogPost other = (BlogPost) obj;
if (equals(other)) {
return 0;
}
return -1;
}
}

Everything looks good.
But, instead of -1 return the following:
public int compareTo(Object obj){
BlogPost other = (BlogPost)obj;
if(equals(other)){
return 0;
}
return mCreationDate.compareTo(other.mCreationDate);
}
If you have any questions feel free to ask!

3,005 PointsThank You sooo much Micheal! it worked. can you please explain why we used that return instead of -1?
// return mCreationDate.compareTo(other.mCreationDate);

24,512 PointsWe want to use compareTo because it returns -1 if the creation date is less than the other.creationDate. It returns 1 if the creation date is greater than other.creationDate. The last task asked us to order the dates in chronological order -- by using compareTo() we can order the dates in chronological order.
How compareTo() works
How Does compareTo() compare Strings?
