Write a Party class with attributes for the number of guests expected and the location of the party. Include getters and setters.

   //setting values
   p.setNumberOfGuests(10);
   p.setLocation("Srinagar");
   d.setNumberOfGuests(15);
   d.setLocation("jk");
   d.setDinnerOption("SeaFood");
  
   //displaying output
       System.out.println(p.getNumberOfGuests());
       System.out.println(p.getLocation());
       System.out.println(d.getNumberOfGuests());
