Vehicle is an interface that declares three methods to: Modify the gear number: sets the gear value to the new value passed as a parameter Modify the speed: increments the Vehicles speed by the value passed Apply the break: will decrement Vehicles speed by the value passed

Car, Boat, Aircraft are three classes that implement Vehicle (They also define the size and color)

Truck, Van, Sailboat, Yacht, Helicopter, and Blimp are classes that inherit the three previous classes as shown in the diagram. (They differ by the size maximum number of passengers- and number of passengers each one has)

Write the java classes that is defined above. With the needed default constructor and at least one overloaded constructor for every class.

Please include all the setter, getter, toString methods Write the tester class that instantiate 3 Objects of each of the Truck, Van, Sailboat, Yacht, Helicopter,

and Blimp classes. For example: Truck C1 = new Truck() Car C2 = new Truck() Vehicle C3 = new Truck()

Invoke all the methods in all the classes, even if it will generate an error. Output the expected results, and the actual ones

For example

System.out.println(Testing getSize() + expected + 2 + passenger );

System.out.println(Testing getSize() + Actual + C1.getSize() + passenger );

If you will expect that invoking a method will give a syntax error, explain why in your out put statement and comment the statement that caused the error.

No need for the users entry. Document your code properly, dont forget @override. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

this is the code I have so far, please help me modify/complete it:

public interface vehicle

//abstract method to be implemented by the subclasses

public void speed(int speed);

}

this.size=size;

this.color=color;
