STUCK!!!! I can't figure out where i have gone wrong. Any suggestion with the right code
package com.example;
import java.util.Arraylist;
import java.io.Serializable;
import java.util.Date;
import java.util.List;
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 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 List<String> getExternalLinks () {
List<String> link = new ArrayList<String> ();
for (String word : getWords()) {
if (word.startsWith("http")) {
link.add(word);
}
}
return link;
}
}

Treehouse TeacherHi there! I received your request for assistance. First, let me say that you're doing terrific!
Now to the problem. You're either going to love or hate this answer. You have a typo in your import
statements.
You typed:
import java.util.Arraylist;
But you meant to type:
import java.util.ArrayList;
Note the capitalization of the "L" in "List" in the second version. When I change that one letter, your code passes the challenge. Well done!

Your errors show that ArrayList
is unknown - that's because your import doesn't have a capital L in it. Change that and your code is fine.
Steve.
