In order to provide a user interface, we need to provide a layer on top of the ParkingOffice class that will accept commands and send them on. This layer will be the ParkingService.
Based on the diagram you should create a parking service class
ParkingOffice.java
public class ParkingOffice {
String name;
String address;
String phone;
String parkingOfficeName;
List<Customer> customers;
List<Car> cars;
List<ParkingLot> lots;
List<ParkingCharge> charges;
public ParkingOffice(){
customers = new ArrayList<>();
cars = new ArrayList<>();
lots = new ArrayList<>();
charges = new ArrayList<>();
}
public Customer register() {
Customer cust = new Customer(name,address,phone);
customers.add(cust);
return cust;
}
public Car register(Customer c,String licence, CarType t) {
Car car = new Car(c,licence,t);
cars.add(car);
return car;
}
public Customer getCustomer(String name) {
for(Customer cust : customers)
if(cust.getName().equals(name))
return cust;
return null;
}
public double addCharge(ParkingCharge p) {
charges.add(p);
return p.amount;
}
public String[] getCustomerIds(){
String[] stringArray1 = new String[2];
for(int i=0;i<2;i++){
stringArray1[i] = customers.get(i).customerId;
}
return stringArray1;
}
public String [] getPermitID () {
String[] stringArray2 = new String[1];
for(int i=0;i<1;i++){
stringArray2[i] = charges.get(i).permitID;
}
return stringArray2;
}
public List<String> getPermitIds(Customer c){
List<String> permitid = new ArrayList<>();
for(Car car:cars){
if(car.owner == c.customerId)
permitid.add(car.permit);
}
return permitid;
}
public String getParkingOfficeName(){
return this.parkingOfficeName;
}
/* Implement the desired park function */
public String park(Date date,String ParkingPermit,ParkingLot pl){
/* to have the amount paid during the transaction for
the specified parking lot */
double amount=pl.amount;
/* to have the date on which the parking lot is booked */

String s="Amount paid on date: ";
s=s+onDate;
s=s+" is "+Double.toString(amount);
s=s+"\nDear customer, your transaction for vehicle with permit ID, ";

return s;
}
public double getParkingCharges (ParkingCharge p ){
if(p.numofHours <= 3) {
