Not sure what Im doing wrong? Bummer! Expected 3 links to be found, but received 0.

the error message is telling me " Bummer! Expected 3 links to be found, but received 0." But I'm not sure why.

com/example/BlogPost.java
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 List<String> getExternalLinks() {
   List<String> results = new ArrayList<String>();
    for (String word : getWords()) {
      if (word.startsWith("https")) {
        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;
  }
}

Hi there....

You had it close. You almost done the challenge. The only thing you did wrong was you use word.startsWith("https") ,it should be http rather than https.

I hope this can help a little. Happy coding
