Hello I need some help with my code.

I need it to call the Payable class computeAmountToPay(); method to show the computed output. Example:

Enter your choice: 1. Add hourly employee 2. Add manager 3. Add sales manager 4. Add bill 5. List all payables 6. Exit 2 Enter the first name. james Enter the last name. turner Enter ID 12 Enter manager's annual salary 12 Enter your choice: 1. Add hourly employee 2. Add manager 3. Add sales manager 4. Add bill 5. List all payables 6. Exit 1 Enter the first name. time Enter the last name. jun Enter ID 234 Enter the hours. 4 Enter the rate 4 Enter your choice: 1. Add hourly employee 2. Add manager 3. Add sales manager 4. Add bill 5. List all payables 6. Exit 5 class edu.seminolestate.employees.Manager [First Name=james, Last Name=turner, Id=12class edu.seminolestate.employees.Manager 0.0 class edu.seminolestate.employees.HourlyEmployee [First Name=time, Last Name=jun, Id=234class edu.seminolestate.employees.HourlyEmployeeHourlyEmployees [ First Name=time, Last Name=jun, ID=234, Pay Rate=4.0, Hours Worked=4.0] Enter your choice: 1. Add hourly employee 2. Add manager 3. Add sales manager 4. Add bill 5. List all payables 6. Exit

THIS SHOULD SHOW HOW MUCH THE HOURLY EMPLOYEE IS TO BE PAYED which is $16. Same for the rest of the options. I have them worked out in the classes but cant figure out how to code this. I THINK I AM HAVING TROUBLE IN THE PRINTEWRITER AREA OF THE APPLICATION.

HERE IS WHAT I HAVE.
