8,108 PointsBummer! Expected 11 words, but received 3.
What did I do wrong? I felt I have done correctly.. What do they means 11 words I cant see that in compiler :S
or do I have to put a variable inside the method? ex. public String[] getword( String x){ ..}
or am I calling wrong variable mBody?
also question nr2. Why couldnt I call \s? I have to type \s+ instead :S really wired is it because we are using JAVA 8 or? Really confusing and I still dont understand what \w means, does that mean that it takes characters/strings/text
help please
package com.example;
import java.util.Date;
public class BlogPost {
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 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 String[] getWords(){
return mBody.split("[^\\w\\s+#@]+");}
}

3,483 PointsYour getWords method expects a List of strings. You need to add the splitted objects to a list before returning. try this:
java... public String[] getWords(){ String[] list = mBody.split("\s+"); return list; } ...

8,108 Pointsplus means .. if you have more than elements in the list .. I guess :)

3,483 PointsI know <i>\s</i> targets spaces in a string, as I've understood... The quiz question was based on making a <i>getter</i> which gets a list og each word in the <i>body</i>. Then if you later wanted to get specific words from the <i>body</i>, you could just <i>iterate</i> that list, by using the <i>getWords()</i> method (called a getter). The pluss sign I don't know.
You could of course have iterated a class field of type list. But the you wouldn't be able to access it from other classes, assuming it would be private for security resons.
