Notes

Amazon is developing a new locker system for Amazon deliveries
to ensure customer packages are delivered in a secure location.

In order to assist delivery drivers, Amazon will develop a software to be installed
that will instruct which locker the driver should place the package in depending on its size.

For the purposes of this question, design and implement the component of this system
that will take a package's size and return the locker number the package should be
stored in so that the customer can be notified where their package is located.

This solution should be able to simulate adding a package to the locker
and removing a package given a locker number.

public class Facility
{
private List<Package> numOfSmallLockers;
private List<Package> numOfMidLockers;
private List<Package> numOfLargeLockers;

public Facility (int numOfSmall, int numOfMid, int numOfLarge)
{
numOfSmallLockers = new ArrayList<>(numOfSmall);
numOfMidLockers = new ArrayList<>(numOfMid);
numOfLargeLockers = new ArrayList<>(numOfLarge);
}

public List<Package> getNumOfSmallLockers()
{
return numOfSmallLockers;
}

public List<Package> getNumOfMidLockers()
{
return numOfMidLockers;
}

public List<Package> getNumOfLargeLockers()
{
return numOfLargeLockers;
}

// public void addPackage
}

public class Packages

{
private int[] lockerNum; // 1-10 11-20 21-30
private String packageSize ; // "S" "M" "L"
private int id;

public PackageLocker (int id,String size)
{
this.id = id;
this.packageSize = size;
