3,545 PointsI am Having trouble implementing comparable
How do we implement the Comparable interface, @Override public int compareTo(Object ob){return 1;} creates an error
package com.example;
import java.lang.Comparable;
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;
}
@Override
public int compareTo(Object blog){
return 1;
}
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;
}
}

56,413 PointsIt's the line that says "public class BlogPost". You put the "implements Comparable" after that and before the curly brace.
