Hi. I just need help on jGRASP where I need to upload files to declare a public class. If you want more information, this is a follow up question from this link:

How do I fix the error in my Java code that says: 'class WatchException is public, should be declared in a file named WatchException.java'? I understand this error means my public class WatchException needs to be in a file named WatchException.java

This is the code: public class Watch { private int wserial; private double wprice; private String wdesc; private int wtype; public Watch(int wserial, double wprice, String wdesc, int wtype) throws WatchException { setSerial(wserial); setPrice(wprice); setDesc(wdesc); setType(wtype); } public void setSerial(int wserial) throws WatchException { if (wserial >= 10001 && wserial <= 99999) { this.wserial = wserial; } else { throw new WatchException("Inval…
