Output seems correct, but test fails on 4th requirement

Question about the task

Implementing an interface using a local class

Java Multithreading, Level 4, Lesson 6

Resolved

Any idea?

In the Cat class, implement the toCanSpeak method's logic, which is described in a Javadoc.

Requirements:

The Cat class must implement a public toCanSpeak method with one int parameter.
The toCanSpeak method must return a CanSpeak object.
If the passed argument is less than 1, the speak() method must return a string formatted as follows: "<name> is sleeping.", where <name> is the name of the current cat.
If the passed argument is greater than or equal to 1, the speak() method must return a string formatted as follows: "<name> says meooow!", where <name> is the name of the current cat, and the number of o's to use in "meow" is equal to the passed parameter.
The program should display data on the screen.

package com.codegym.task.task24.task2407; import java.util.List; /* Implementing an interface using a local class */ public class Solution { public static void main(String[] args) { List<Pet> pet = Util.getPets(); List<CanSpeak> pets = Util.convertPetToCanSpeak(pet); Util.printDialog(pets); } }

When you use a Stringbuilder you appende the "o" and it passes.

Yes... I saw that on the help topic of the next task. I tried here and it worked. Thanks!

It looks like 1 too many o's are being output.

Yes, I noticed that after testing some times. But I still have no idea how to solve it. Can you help me? And other thing: "The toCanSpeak method must return a CanSpeak object.". Is my return correct? Thanks.

In the help session of the next task I saw that they use StringBuilder. I tried here and it worked.

The method is returning a CanSpeak object (the created CatPet class implements this), however it may be a better solution to return an anonymous CanSpeak class with the code from the speak() method that is currently inside the CatPet class. So:

public CanSpeak toCanSpeak(final int i) {
   return new CanSpeak() {
      // the code from the CatPet class
   };
}

You would still need to fix the amount of o's (check the for loop) added to "meooooow!"

Ohh I see. Yes, for some reason I thought that the return should be something like this. But I passed with the "new CatPet();". And the "oooooo" problem was solved by using StringBuilder. Thanks again, Guadalupe!
