# Vehicle-Management-System
a real-world example question that involves both method overloading and method overriding in Java:
## Question: Vehicle Management System
### Problem Statement
You are tasked with developing a simple vehicle management system for a vehicle rental company. The system needs to manage different types of vehicles and calculate rental costs based on the type and rental duration. You need to implement the following:
1. **Vehicle Class**:
- A base class `Vehicle` with attributes `make`, `model`, and `year`.
- A method `getRentalCost(int days)` to calculate the rental cost.
2. **Car and Bike Classes**:
- Two derived classes `Car` and `Bike` that inherit from `Vehicle`.
- Override the `getRentalCost(int days)` method to provide specific rental cost calculations for cars and bikes.
3. **Rental Cost Calculation**:
- The base `Vehicle` class should provide a default rental cost calculation.
- The `Car` class should charge a flat rate per day plus an additional fee for each day.
- The `Bike` class should charge a flat rate per day with no additional fees.
4. **Method Overloading**:
- Overload the `getRentalCost` method in the `Vehicle` class to allow calculating the rental cost for both days and hours. The method `getRentalCost(int days, int hours)` should calculate the cost by converting hours to a fraction of a day.
### Requirements
1. **Vehicle Class**:
- Attributes: `make` (String), `model` (String), `year` (int).
- Methods:
- `getRentalCost(int days)`: Returns the rental cost for the given number of days.
- `getRentalCost(int days, int hours)`: Returns the rental cost for the given number of days and hours.
2. **Car Class**:
- Inherits from `Vehicle`.
- Overrides `getRentalCost(int days)` to charge $50 per day plus $20 additional fee for each day.
3. **Bike Class**:
- Inherits from `Vehicle`.
- Overrides `getRentalCost(int days)` to charge $20 per day with no additional fees.
4. **Main Program**:
- Create instances of `Car` and `Bike`.
- Demonstrate method overloading and overriding by calculating rental costs for different durations.
### Example Output
```
Car Rental for 3 days: $210
Car Rental for 2 days and 12 hours: $180
Bike Rental for 3 days: $60
Bike Rental for 2 days and 12 hours: $50
```
### Explanation of Features
1. **Method Overloading**:
- The `getRentalCost(int days)` method is overloaded with another method `getRentalCost(int days, int hours)` in the `Vehicle` class to handle both days and hours.
2. **Method Overriding**:
- The `Car` and `Bike` classes override the `getRentalCost(int days)` method from the `Vehicle` class to provide specific rental cost calculations.
This example allows you to demonstrate understanding and implementation of both method overloading and overriding in a practical scenario.
