Hi, I've been stuck on this one all day and I haven't been able to figure it out. I did try interneting around, StackOverflow and the forums here. If anyone has a good solution, please include an explanation if you can because I know I'm missing something here. Thank you!
package com.example;
import java.util.Date;
public class BlogPost {
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 int compareTo(Object obj) {
BlogPost other = (BlogPost) obj;
if (equals (other)) {
return 0;
}
}
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;
}
}

36,222 PointsSure enough, as soon as I asked, I figured it out.
public int compareTo(Object obj){
BlogPost other = (com.example.BlogPost) obj;
if(equals(other)){
return 0;
}
int dateComp = mCreationDate.compareTo(other.mCreationDate);
return 1;
}
