1. Write an abstract superclass called Vehicle that contains the following private data fields: color: a string that holds the color of the vehicle. dateMade: the date the vehicle was manufactured. Provide appropriate constructors and setter/getter methods for this class. Include an abstract void method named steer(). 2. Define an interface named Drivable that contains an abstract method named howToDrive() with return value type String. 3. Write a concrete subclass named Car that extends the Vehicle class and implements the Drivable and Comparable interfaces. (i) The class should contain a String data field: model and an integer data field: speed. Provide appropriate constructors and setter/getter methods for this class. (ii) (iii) (iv) (v) Override the equals method in the Object class. Two Car objects are equal if their models are the same. Implement the steer() method to display "Turn steering wheel." Implement the howToDrive() method that returns a string "Step on gas pedal." Implement the compareTo method to compare two cars on the basis of speed. 4. Write a test program to test your classes and interface. 1.
