I get 22 errors, about not convertable types in my workspace code. I cannot figure out what it can be.

Hi!

Here I posting my code wich I still cant figure it what went wrong.

package com.teamtreehouse;

import java.util.Date;

public class Treet implements Comparable // Samma namn som filen {

private String mAuthor; private String mDescription; private Date mCreationDate;

public Treet(String Author, String Description, Date CreationDate) {

mAuthor = Author; // ?? = Måste vara lika som argumentlistan
mDescription = Description; // ?? = Måste vara lika som argumentlistan
mCreationDate = CreationDate; // ?? = Måste vara lika som argumentlistan

} @Override public String toString() {

return String.format("Treet: \"%s\" by %s on %s, mDescription, mAuthor, mCreationDate);

}

@Override public int compareTo(Object obj) {

Treet other = (Treet) obj;
if (equals(other))
{

  return 0;

}

int dateCmp = mCreationDate.compareTo(other.mCreationDate);
if (dateCmp == 0)
{
  return mDescription.compareTo(other.mDescription);
}
  return dateCmp;

}

public String getAuthor() { return mAuthor; }

public String getDescription() { return mDescription; }

public Date getCreationDate() {

return mCreationDate;

}

public String[] getWords() {

return mDescription.toLowerCase().split("[^\\w#@']+");

}
}

Regards Henrik

Thanks. I will list a couple of things you can look at, in the end of my answer you will see how I would resolve them in code:

It appears like you have commented out the opening curly brace (that is { is in a comment and not a part of the code).

In your toString-method you use a String.format which has an opening quotation mark but not a closing one.

In regards to your parameters' name, name them as any variable, with an initial lowercase, String Author should be String author. It's not something the compiler wouldn't allow, but it's a formality issue.

I don't know how your Example.java looks like (or wherever your main-method is), but remember to import com.teamtreehouse.Treet

So here's how I solved your code:

package com.teamtreehouse;
import java.util.Date;

public class Treet implements Comparable { // the curly brace is now on the right side (that is to the left) of the comment

  private String mAuthor; 
  private String mDescription; 
  private Date mCreationDate;

  public Treet(String author, String description, Date creationDate) { // following the standard of camelCase where initial letters are lowercase

    // The variables below are matched with the arguments of the the constructor. You could match the variable mAuthor
    // with description, since they are both of type String, but that would just be confusing.
    mAuthor = author; 
    mDescription = description;
    mCreationDate = creationDate;
  } 

  @Override 
  public String toString() {
    // added a quotation mark to close the string below
    return String.format("Treet: \"%s\" by %s on %s", mDescription, mAuthor, mCreationDate);  
  }

  @Override 
  public int compareTo(Object obj) {
    Treet2 other = (Treet2) obj;
    if (equals(other)) {
      return 0;
    }
    int dateCmp = mCreationDate.compareTo(other.mCreationDate);
    if (dateCmp == 0) {
      return mDescription.compareTo(other.mDescription);
    }
    return dateCmp;
  }

  public String getAuthor() { 
    return mAuthor; 
  }

  public String getDescription() { 
    return mDescription; 
  }

  public Date getCreationDate() {
    return mCreationDate;
  }

  public String[] getWords() {
    return mDescription.toLowerCase().split("[^\\w#@']+");
  }
}

If you need help with your Example.java you can post that as well.
Good luck Henrik, and have fun. Any more questions, just ask.

All the course have gone quiet well, till I hit into this errors. I have even sorted out earlier errors before. Just that this time I cant find the logical reasons for this errors since the code is matching the one Craig is doing in the video. I will look through the code with your added comments and try again.

Thanks for helping me! Henrik

Adding that doublequot solved all of it!

public String toString() {

return String.format("Treet: \"%s\" by %s on %s", mDescription, mAuthor, mCreationDate);

}

Yes, I have been trying to work with IDE little before I started here on treehouse. But I wanted to get some good teaching in the programming and get all I need to become what I want. :)
