I don't know what is the problem.

Best answer

The link you provided is broken. (Here is an example of a working link.)

Click on the SHARE button (3 to the right from the RUN button) and get the link from there to your project.

OnlineGDB doesn't like when the Main class is in a package. Just remove the

package person;

line from both of your files and after this, your program will run.

That being said, it doesn't mean it works correctly. For instance, it will throw a NullPointerException as your p is set to a new array or Persons, but the individual elements in the array are not initialized (are null) and trying to access them in details() function leads to the aforementioned exception.

If you fix that, you'll run into a ArrayIndexOutOfBoundsException in your sortByHight() function.

I stopped checking for more problems at this point.

Keep an eye open for those pesky bugs! :)
