UML diagram for project 2

Implement the 3 classes in the UML diagram above. More details are below.

You may add any additional *non-public* methods that you want (including 'package protected'

The Child Class:

Needs to have the five instance variables and one class/static variable shown in the diagram
nextID is the class variable.
The constructor should take three parameters.
it must initialize the instance variable Name with the name param
it must initialize the instance variable siblingInProgram with the siblingPlan param
it must initialize the instance variable age with the currentAge param
initialize the yearsOfAttendance instance variable to 0
the dayCareID instance variable should be assigned the value of the nextID static class variable
the nextID class variable should be incremented.
The CalculateBill method should
charge according to the following schedule:
Age	Rate
birth to 1 year	400
1-2 years	300
3-4 years	200
over 4	150
 If the child has a sibling in the program, give the child a 10% discount
After the sibling discount, give the child an additional $10 discount for every year of attendance.
The DayCareWorker Class:

Needs to have 3 instance variables as per the diagram
The constructor should take two parameters
the Name instance variable should be initialized by the name parameter
the salary instance variable should be initialized by the startingPay parameter
thechildrenInGroup instance variable should be initialized to a new ArrayList of Child (which is currently empty)
The performanceReview method
 generate a random number from 1-5 (representing poor, below expectations, meets expectations, exceeds expectations and spectacular),
based on the performance review, increase the salary of the dayCareWorker
Review	Salary increase
poor (1)	0%
below Expectations(2)	1%
Meets Expectations(3)	2.5%
Exceeds Expectations (4)	3.5%
Spectacular (5)	5%
The performFireDrill method
loops through all of the children in the group and report (print) that they are safe
The getXXX methods
accessor for the correct instance variable.
the RemoveChild method (note diagram incomplete!!!! the return type is Optional<Child>)
look through the childrenInGroup list and find the child with the matching id. remove the child from the childrenInGroup list and return an Optional containing that child, if the child is not in the list return an Optional of null.

The DayCareFacility Class:

Needs two instance variables as specified in the diagram.
The main function ( public static void main)
must only have two lines:
create a new DayCareFacility Object
call runDayCare on that object
The constructor
must initialize the two instance variables to new empty arrayLists of the appropriate type
The runDayCare method:
feel free to break this method into pieces and make private methods to do parts of what is listed here. (and just call those private methods from this one)
needs to display the top level menu which  should provide the following options: (give visual feedback to the user for each)
Admit Child
prompt the user to enter the details you need
create a new child object
randomly select a dayCareWorker from the  list to be the worker assigned to that child.
add the child to the list of children instance variable

hire worker
prompt the user to enter the details that you need
create a new DayCareWorker object
add the worker to the list of workers instance variable
Students go to school
all of the students who are 6 or older should be removed from the system - both from the lists in the DayCareFacility and from the DayCareWorkers lists
RunFireDrill
call the fireDrill method on each DayCareWorker
exit
end the program
End of year:
go through all the students and add one to their age and add one to their years at the facility
go through all of the DayCareWorkers and call their performance review method
DoAccounting
run calculateBill on all the students and getSalary on all of the workers and see of the facility is making or losing money (is the total salary less or more than the total bills.) report this to the user.
