hey there, in past few hours i have already got the code for this one but that dosnt work properly. Please help me to solve this.

a. Create a class named Salesperson. Data fields for Salesperson include an integer ID number and a double annual sales amount. Methods include a constructor that requires values for both data fields, as well as get and set methods for each of the data fields. Save the file as Salesperson.java.

b. Create an application that allows a user to enter values for an array of seven Salesperson objects. Offer the user the choice of displaying the objects in order by either ID number or sales value. Save the application as SalespersonSort.java.
