Java Java Data Structures - Retired Organizing Data Splitting Strings

not sure why the regex isn't working

the question is

Add a new method named getWords that returns the words from the body of the blog post. Since we don't need to worry about special characters, let's just use the regular expression pattern \s+ (or any one or more white space character) for the parameter to the split method. (Remember to escape the backslash in your Java code.

com/example/BlogPost.java
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(\\s+);
  }
}

You doing great!! , it is just need to be surround with ""

Code is here : https://gist.github.com/juthawong/392a2bdc3c3ad2b244b9

I tried this, but it doesn't seem to work

Oh Another things .

You have to change

public String getWords () { return mBody.split(\s+); }

to

public String[] getWords(){ return mBody.split("\s+");

}

The split will always split to String array not String :D

thank you, makes sense that the split is in an array
