1,128 PointsI keep getting the : "Did you forget to add getExternalLinks method." But i did create it.
public List<String> getExternalLinks(String[] array) { List<String> list = new ArrayList<String>(); for (String word : array) { if (word.startsWith("http")) { list.add(word); } } return list; }
Did i miss something. Code does compile.
package com.example;
import java.io.Serializable;
import java.util.Date;
import java.util.List;
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> getExternalLinks(String[] array) {
List<String> list = new ArrayList<String>();
for (String word : array) {
if (word.startsWith("http")) {
list.add(word);
}
}
return list;
}
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;
}
}

the getExternalLinks method doesnΒ΄t need an argument.
For the for loop you can use the getWord() method to get the BlogPost words
Your code can look like this:
public List<String> getExternalLinks() {
List<String> list = new ArrayList<String>();
for (String word : getWords()) {
if (word.startsWith("http")) {
list.add(word);
}
}
return list;
}
Makes sense?
