I don't understand part 3 of this question at all. There does not seem to be a good answer anywhere on the forum.

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; }

}

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;
}

}

So you're code looks right, minimum needed to complete the challenge was:

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) {
    this.mAuthor = author;
    this.mTitle = title;
    this.mBody = body;
    this.mCategory = category;
    this.mCreationDate = creationDate;
  }

  public String getBody() {
    return mBody;
  }

}

Are you confused as to why you need a getter method? If so, the member variables for the BlogPost class are all private. That means that if you create a BlogPost object, you will not be able to access those variables without some public way of getting to them. That is why you need the getter methods. By creating a public method (for both getters and setters), we can control what private BlogPost variables can be get or set and how we will allow them to be get or set.

Do you have any additional questions about this challenge or Java objects in general?
