This is what my ApiResponse.java file looks like:

package com.teamtreehouse.testing;

public class ApiResponse {
    private final int statusCode;
    private final String body;

    public ApiResponse(int statusCode, String body) {
        this.statusCode = statusCode;
        this.body = body;
    }

    public int getStatusCode() {
        return statusCode;
    }

    public String getBody() {
        return body;
    }
}

All the code checks out here, I had to make a few tweaks to the package, as my structure was different.

e.g. package com.teamtreehouse.courses; instead of package com.teamtreehouse.courses.model;

I got the exact same error. Did you find out what the problem was?
