Cannot split string mBody.

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+");
