Made this program using Java Consider a parking lot for various types of cars (motorcycles, cars, buses). There are the following assumptions as below:The parking lot has multiple levels. Each level has multiple rows of spots. The parking lot has motorcycle spots, compact spots, and large spots. A motorcycle can park in any slot. A car can park in either a single compact spot or a single large spot. A bus can park in five large spots that are consecutive and within the same row; it cannot park in small spots.

Algorithm: Parking Lot Management1. Define an enum class called VehicleType with values MOTORCYCLE, COMPACT_CAR, LARGE_CAR, and BUS.2. Define a class named ParkingSpot with the following attributes: - spotNumber: an integer to represent the spot number. - vehicleType: a VehicleType enum to specify the type of vehicle the spot can accommodate. - isOccupied: a boolean to indicate if the spot is occupied.3. Create methods in the ParkingSpot class: - isOccupied(): Returns true if the spot is occupied; otherwise, false. - canFit(VehicleType type): Checks if the spot can accommodate the given vehicle type and is unoccupied. - occupy(): Marks the spot as occupied. - vacate(): Marks the spot as unoccupied.4. Define a class named Row to represent a row of parking spots. Each row can have spots for a specific type of vehicle.5. Create a constructor for the Row class that initializes a list of ParkingSpot objects based on the number of spots and the specified vehicle type.6. Implement a park(VehicleType type) method in the Row class to find an available spot for the given vehicle type and mark it as occupied.7. Define a class named Level to represent a level of the parking lot. Each level consists of multiple rows of parking spots.8. Create a constructor for the Level class that initializes a list of Row objects, with different vehicle types, to represent the parking spots on the level.9. Implement a park(VehicleType type) method in the Level class that searches for an available spot for the given vehicle type in its rows and marks it as occupied.10. Define a class named ParkingLot to manage the entire parking lot. It consists of multiple levels.11. Create a constructor for the ParkingLot class, which initializes a list of Level objects to represent the parking levels.12. Implement a parkVehicle(VehicleType type) method in the ParkingLot class that searches for an available spot for the given vehicle type on any level and marks it as occupied.13. In the main application (e.g., Main.java), create a ParkingLot instance and demonstrate the functionality by parking various types of vehicles using the parkVehicle method.14. Display the results to indicate whether the parking was successful and provide information about the parked vehicles.15. Compile and run the Main class to execute the parking lot management system.16. Handle any errors or exceptions that may occur during the execution of the program.1public enum VehicleType { 2 MOTORCYCLE, 3 COMPACT_CAR, 4 LARGE_CAR, 5 BUS 6} 71public class ParkingSpot { 2 private int spotNumber; 3 private VehicleType vehicleType; 4 private boolean isOccupied; 5 6 public ParkingSpot(int spotNumber, VehicleType vehicleType) { 7 this.spotNumber = spotNumber; 8 this.vehicleType = vehicleType; 9 this.isOccupied = false; 10 } 11 12 public boolean isOccupied() { 13 return isOccupied; 14 } 15 16 public boolean canFit(VehicleType type) { 17 return (vehicleType == type && !isOccupied); 18 } 19 20 public void occupy() { 21 isOccupied = true; 22 } 23 24 public void vacate() { 25 isOccupied = false; 26 } 27} 281import java.util.ArrayList; 2import java.util.List; 3 4public class Row { 5 private List<ParkingSpot> spots; 6 7 public Row(int numberOfSpots, VehicleType vehicleType) { 8 spots = new ArrayList<>(); 9 for (int i = 1; i <= numberOfSpots; i++) { 10 spots.add(new ParkingSpot(i, vehicleType)); 11 } 12 } 13 14 public ParkingSpot park(VehicleType type) { 15 for (ParkingSpot spot : spots) { 16 if (spot.canFit(type)) { 17 spot.occupy(); 18 return spot; 19 } 20 } 21 return null; // No available spot for the given vehicle type 22 } 23} 241import java.util.ArrayList; 2import java.util.List; 3 4public class Level { 5 private List<Row> rows; 6 7 public Level(int numRows, int spotsPerRow) { 8 rows = new ArrayList<>(); 9 for (int i = 0; i < numRows; i++) { 10 rows.add(new Row(spotsPerRow, VehicleType.MOTORCYCLE)); 11 } 12 for (int i = 0; i < numRows; i++) { 13 rows.add(new Row(spotsPerRow, VehicleType.COMPACT_CAR)); 14 } 15 for (int i = 0; i < numRows; i++) { 16 rows.add(new Row(spotsPerRow, VehicleType.LARGE_CAR)); 17 } 18 } 19 20 public ParkingSpot park(VehicleType type) { 21 for (Row row : rows) { 22 ParkingSpot spot = row.park(type); 23 if (spot != null) { 24 return spot; 25 } 26 } 27 return null; // No available spot for the given vehicle type 28 } 29} 301import java.util.ArrayList; 2import java.util.List; 3 4public class ParkingLot { 5 private List<Level> levels; 6 7 public ParkingLot(int numLevels, int numRowsPerLevel, int spotsPerRow) { 8 levels = new ArrayList<>(); 9 for (int i = 0; i < numLevels; i++) { 10 levels.add(new Level(numRowsPerLevel, spotsPerRow)); 11 } 12 } 13 14 public ParkingSpot parkVehicle(VehicleType type) { 15 for (Level level : levels) { 16 ParkingSpot spot = level.park(type); 17 if (spot != null) { 18 return spot; 19 } 20 } 21 return null; // No available spot for the given vehicle type 22 } 23} 241public class Main { 2 public static void main(String[] args) { 3 ParkingLot parkingLot = new ParkingLot(3, 5, 10); 4 5 // Example usage: 6 ParkingSpot motorcycleSpot = parkingLot.parkVehicle(VehicleType.MOTORCYCLE); 7 if (motorcycleSpot != null) { 8 System.out.println("Parked a motorcycle in spot " + motorcycleSpot); 9 } else { 10 System.out.println("No available spot for motorcycles."); 11 } 12 13 ParkingSpot busSpot = parkingLot.parkVehicle(VehicleType.BUS); 14 if (busSpot != null) { 15 System.out.println("Parked a bus in spot " + busSpot); 16 } else { 17 System.out.println("No available spot for buses."); 18 } 19 } 20} 21Output :
