Vehicle Speed Calculator in Java: Explanation & Practice

Calculate max speeds for different vehicles

Problem summary

Create Vehicle hierarchy where each type has different speed calculation based on attributes.

Starter code

// Vehicle: abstract getMaxSpeed()
// Car: horsePower * 0.5
// Motorcycle: horsePower * 0.7
// Bicycle: gears * 5

public class Main {
    public static void main(String[] args) {
        // Test case 1: Car with 200 HP
        // Print: Max speed: <result> km/h
    }
}

Expected output and test cases

Car 200 HP
```
Max speed: 100.0 km/h
```
Motorcycle 200 HP
```
Max speed: 140.0 km/h
```
Bicycle 21 gears
```
Max speed: 105.0 km/h
```

Hints

Each vehicle calculates speed differently
Store relevant attributes in each class
Override getMaxSpeed() method
