i think solution is correct i don't know why the errors are occuring

// missing return statement

com/example/BlogPost.java
package com.example;
import java.util.ArrayList;
import java.util.Arrays;
import java.io.Serializable;
import java.util.Date;

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 ArrayList getExternalLinks() {
    ArrayList<String> links = new ArrayList<String>();
     for (String word : getWords()) {
          if (word.startsWith("http")) { 
               links.add(word);
          } 
          return links; 
     }
}

  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;
  }
}

Your return statement is inside the for loop, so it will return after checking only the first word. You should probably also have the return type as List<String> instead of ArrayList.
