1,283 PointsError: Task 1 is no longer passing but after going back to Task 1 it's actually passing wtf?!
And in that case I don't have any preview to the console where I would expect to see compilation errors.
Could anyone take a look at my code and tell me what did I do wrong?
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;
}
@Override
public int compareTo(Object obj){
if(((BlogPost)obj).equals(obj)){
return 0;
}
return 1;
}
}

@Override
public int compareTo(Object obj){
if(((BlogPost)obj).equals(obj)){//<-- this is not how you cast an Object and sure is not how equals work
return 0;
}
return 1;
}
This is the revision version of your code:
@Override
public int compareTo(Object obj) {
BlogPost blogPost = (BlogPost) obj;//<-- this is casting
if(equals(obj)){//<-- this is how to use equals
return 0;
}
return 1;
}
please try it and I hope it will work. I hope this helps a little.
