Why isn't this verifying?

Question about the task

Resolved

I get the following error messages: Be sure that the ImageReaderFactory class has a getImageReader() method. The getImageReader method must return a BmpReader object when ImageTypes.BMP is passed as an argument. Be sure that the getImageReader method works correctly if null is passed to it.

1. Take a careful look at the classes you have.
2. In separate files in the common package, create JpgReader, PngReader, and BmpReader classes that implement the ImageReader interface.
3. In a separate file in the main package, create the ImageReaderFactory class with one method.
3.1. Think about what it should be called.
3.2. Think about which modifiers this method should have.
4. This method should:
4.1. For each value in ImageTypes, return the appropriate Reader. For example, for
ImageTypes.JPG, return a JpgReader;
4.2. If an invalid argument is passed, then throw an exception:
IllegalArgumentException("Unknown image type").

Requirements:

Create a JpgReader class in the common package. It must implement the ImageReader interface.
Create a PngReader class in the common package. It must implement the ImageReader interface.
Create a BmpReader class in the common package. It must implement the ImageReader interface.
Create a public class named ImageReaderFactory.
Add a public static method getImageReader with an ImageTypes parameter to the ImageReaderFactory class.
The getImageReader method must create and return a suitable Reader.
The getImageReader method must throw an IllegalArgumentException if an invalid argument is passed.

Condition #3 " In a separate file in the main package, create the ImageReaderFactory class with one method." Check what package your IRF class is in

Good night, what a simple mistake. Thanks.

Isn't it all under the same package?
