How do I prevent the return statement from breaking up words onto different lines?

I know that %n can be used for print statements but I can't get the same to work when returning the tweet. Mine comes up as this...

This is a new Treet: Treet: "Want to be famous? Simply tweet about java and u se the hashtag #treet. I'll use your tweet in a new @treehouse course about d ata structures." - @craigsdennis

The spaces indicate where it breaks up the word onto the next line.

Hi GAI-EWB Team

Are you able to post your code up so I can test it and try to identify where the issue may be?

Thanks Stephen

So we have 2 classes (in the same package): Treet.java and a Main.java (which in the video lessons is the Example.java).

My Treet.java looks like this:

public class Treet {

    private String mAuthor;
    private String mDescription;

    public String getAuthor() {
        return mAuthor;
    }

    public String getDescription() {
        return mDescription;
    }

    public Treet(String author, String description) {
        mAuthor = author;
        mDescription = description;     
    }

    @Override
    public String toString() {
        return "Treet: " + mDescription + " -@" + mAuthor;

    }
}

And the Main.java looks like this:

public class Main {

    public static void main(String[] args) {

        Treet treet = new Treet(
                "craigsdennis",
                "\"Want to be famous? Simply tweet about java and u"+
                "se the hashtag #treet. I'll use your tweet in a new @treehouse course about d"+
                "ata structures.\"");

        System.out.printf("This is a treet: %n %s", treet); // see how the next line appears in output
        System.out.println("");
        System.out.println("");
        System.out.printf("This is a treet: %n%s", treet); // see how the next line appears in output
    }

}

Then my output is the following:

This is a treet: 
 Treet: "Want to be famous? Simply tweet about java and use the hashtag #treet. I'll use your tweet in a new @treehouse course about data structures." -@craigsdennis

This is a treet: 
Treet: "Want to be famous? Simply tweet about java and use the hashtag #treet. I'll use your tweet in a new @treehouse course about data structures." -@craigsdennis

So if I understand you correctly, did you use %n in the Treet constructor's description string in the Main.java class? I guess it is not necessary as you can see from my code.

Can you post your code, if I misunderstood something?

The issue may be that you actually use a %n where you actually break up the code in the editor for better readability. In this case, I would say this is not necessary and this is probably the reason why you get the spaces in the words as you described in your question. You should omit the %n in those places as I did.
