4,584 PointsHmmm I think you might have understood the challenge wrong. It wants you to check if it is a string and then cast it to a string if it is.
public static String getTitleFromObject(Object obj) {
// Fix this result variable to be the correct string.
String result = "";
if(obj instanceof String){
result = (String) obj;
}
return result;
}
That is the first part of the challenge.
