Need Help in Java in english I am useing Java SDK and Eclipse IDE for Java

You operate several hot dog stands distributed throughout town. Define a class named HotDogStand that has an instance variable for the hot dog stands ID number and an instance variable for how many hot dogs the stand has sold that day. Create a constructor that allows a user of the class to initialize both values. Also create a method named justSold that increments by one the number of hot dogs the stand has sold. 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 method 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 variety of HotDogs. Your main method should asks user to enter command. A command can be "sold", which in result would ask for cart number and increment its pointer. Another command can be "print", which will also asks for cart number and print how many hotdogs that cart sold. One command would be "print-all", that will result in printing how many HotDogs were sold by all carts. Call Static method of HotDogStand for "print-all". Lastly, anything else will terminate the program.
