There are a couple of issues:

  1. You have placed the constructor and the getters outside the body (the {} brackets) of the class. Which is not correct since they belong to the class.

  2. A constructor has to be named exactly the same as the class it is placed in, since the class is named BlogPost the constructor has to be named that too. So Treet is not an acceptable name.

Also while not a direct issue you have added way more code than was asked for. Task 2 only asks you to add a constructor, not to add getters for all the properties. Task 3 does ask you to add a getter but only for the body field. Adding more code than is asked for can often lead to issues as the code checker for these challenges tend to be pretty strict. So I'd advise not doing so in the future.

If you fix the issues I have outlined like this:

package com.example;

import java.util.Date;

public class BlogPost { // This starts the body of the BlogPost class
  private String mAuthor;
  private String mTitle;
  private String mBody;
  private String mCategory;
  private Date mCreationDate;

  public BlogPost(String title, String author,String body,String category,Date creationDate){
    mTitle = title;
    mAuthor = author;
    mBody= body;
    mCategory = category;
    mCreationDate = creationDate; 
  }
  public String getBody(){
    return mBody;
  }
} // This ends the body of the BlogPost class

Then your code will pass the challenge.
