dear someone who can help
The first attachment is the program i wrote the second attachment is
the
required guidelines from the instructor.

also i don't know if i wrote the program correctly the instructions are
as
follows :You operate several hot dog stands . Define a class named
HotDogStand that has a member variable for the hot dog stand's Id nmber
and
a member variable for how many hot dogs the stand has sold that day.
Create
a constructor that allow a user of the class to initialize both values.
Also create a method named justSold that increments the number of hot
dogs
the stand has sold by one. The idea is that this method will be invoked
each
time the stand sells a hot dog so that you can track the total number
of hot
dogs sold by the stand. Add another method that returns the number of
hot
dogs sold.
Finally add a static variable that tracks the total number of hot dogs
sold
by all hot dog stands and a static variable that returns the value in
this
variable.
Write a main method to test your class with at least three hot dog
stands
that each sell a varity of hot dogs . We had to call this one public
class
program2JS. the JS is our initials. I really need help with this i'm
not
sure i even wrote it correctly thanks Judith Spurlock my email address
is
jspurlock83@hotmail.com

the compile code that i'm getting is as follows
unexpected type required variable s1.getTotalSold() = s1.getNumSold +
s2.getNumSold + s3.getNumSold;
also i don't know what code to put in the public void justSold() and i
don't know how to add justSold each time something is sold to the
getNumSold and i don't know what to program in the public void
justSold() any suggestions or help please judith the program is below
