9,260 PointsDid I miss importing something?
I looked at the logic for getWordsPrefixedWith in the video, but am still confused as to what I'm missing in the code challenge here.
package com.example;
import java.io.Serializable;
import java.util.Date;
import java.util.ArrayList;
public class BlogPost implements Comparable<BlogPost>, Serializable {
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(BlogPost other) {
if (equals(other)) {
return 0;
}
return mCreationDate.compareTo(other.mCreationDate);
}
public List<String> getWords() {
return getWordsPrefixedWith("\\s+");
}
public List<String> getExternalLinks(){
return getWordsPrefixedWith("http");
}
private List<String> getWordsPrefixedWith(String prefix){
List<String> results = new ArrayList<String>();
for (String word: getWords()){
if (word.startsWith(prefix)){
results.add(word);
}
}
return results;
}
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;
}
}

Treehouse Project ReviewerYou're using List<> in your method so you have to make sure to
import java.util.List;
