We have a parking office class for an object-oriented parking management system using java

• 
  
  
  
  • Add (implement )a method to the Parking Office c to return a collection of customer ids (getCustomerIds) using java
  
  
  
  

I have attached two class diagrams with definitions of all related classes in our system (i.e car, customer, .....).

Parking office methods in the class defination like

register, getcustomer and addcharge
have already been implemented, we just need an additional getcustomerID method as mentioned above
