Vehicle part 3.

This task has the following elements that are relevant to the learning outcomes of this module: - be able to define common behavior for objects using interface - be able to define interfaces and classes that implement these - have knowledge of differences and differences between specific & abstract classes and interfaces - have knowledge of version control systems with special focus on GIT - could use the most common GIT methods in connection with program development You will continue to develop a console-based system that records vehicle information. Now let the Vehicle implement a Driveable interface that defines some constants and methods (see below). This task constitutes the third part of the GIT task and will be developed in branch "part3" remember to push it to your repository and then merge the master with it before continuing with the next task. The program should be developed gradually and in the third section you will: Vehicle: Implementable Driveable interface. Implement the stop () method defined in Driveable, it should set speed to 0 and print a message about it to the console. Car and Bicycle: They will implement the two other methods, accelerate (double factor) and breaks (double factor). factor defines how fast the vehicle accelerates or stops, but it has different effects. Car: If the car is at rest and starts to accelerate then it will get a speed equal to: 0.5 * factor, otherwise it will get speed equal to: speed * factor. The speed of car cannot exceed the speed defined in MAX_SPEED_CAR. When the car stops, it will get speed equal to: speed / factor no matter how fast it had moved before. Bicycle: If the bike is at rest and starts to accelerate then it will get a speed equal to: 0.3 * factor, otherwise it will get speed equal to: speed * 0.5 * factor. The speed of the bike cannot exceed the speed defined in MAX_SPEED_BIKE. When the bike stops it will get speed equal to: speed / (factor * 0.5) no matter how fast it had moved before. Both classes will also print the speed of the vehicle after it has accelerated / stopped. TestVehicles: Must get an additional choice "Test driveable interface" to test methods defined in Driveable. This test should preferably be hard-coded, it creates a new Car and Bicycle object, they accelerate, stop them a bit and stop them altogether.

Example of the application's print is:

1 ................................... New car 2 ........... .................... New bicycle 3 ...................... Find vehicle by name 4 .............. Show data about all vehicles 5 ....... Change direction of a given vehicle 6 ................ ......... Test clone method 7 .................. Test driveable interface 8 ............... ............... Exit program ............................. Your choice? 7 Car: Vehicle accelerated to: 5.00 km / h Vehicle accelerated to: 250.00 km / h Vehicle slowed down to: 0.25 km / h Vehicle stops Bicycle: Vehicle accelerated to: 3.00 km / h Vehicle accelerated to: 100.00 km / h Vehicle slowed down to: 0.20 km / h Vehicle stops

Driveable Interface:

public interface Driveable { double MAX_SPEED_CAR = 250.00 ; double MAX_SPEED_BIKE = 100.00 ; void accelerate ( int speed factor ) ; void breaks ( int speed factor ) ; void stop () ; }
