Java Java Data Structures - Retired Organizing Data Splitting Strings

In the getWords() method, it returns an array of String, why it prompted that 11 words were expected?

I passed parameters by BlogPost constructor, please check my 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(){
    BlogPost blogpost = new BlogPost("asdf", "asdf fd ds", "fd dfs sdf  fdfd ", "et we fdsa   sdf  dsa", new Date());
    String[] abc = blogpost.getBody().split("\\s+");
    return abc;
  }
}

Hi Tan

You do not need to write this much code. Moreover since you are still in the same class there is no need to call the getBody() method to gain the mBody String variable from the same class. Here is my revision for your original code.

 public String[] getWords(){
/*You do not need all of these code:
    BlogPost blogpost = new BlogPost("asdf", "asdf fd ds", "fd dfs sdf  fdfd ", "et we fdsa   sdf  dsa", new Date());
    String[] abc = blogpost.getBody().split("\\s+");
    return abc;
*/
//All you need is to code:
    return mBody.split("\\s+");
  }

PS: do not forget to import java.util.Arrays; since you want to return arrays of Strings.

I hope this can help a little.

try this. Need to add a ^ in the regex expression.

return mBody.split("^\s+");
