write a java programme: Vehicle class: First create an abstract Vehicle class that contains code common to all of the vehicles. 1. Vehicle class has a color, IDnumber, and a model. 2. Throw an exception named “InputNotCorrectException” if the IDnumber is negative. 3. The accessor and mutator methods for all three data fields. 4. Also include a void wheels() method which is declared abstract. Runnable interface: 1.Deaclare an abstract method named HowToRun() which has a return type of void. Car class: Car class is a subclass of Vehicle which implements the Runnable interface. 1. Write a class called Car which extends the Vehicle class and implements the Runnable interface. 2. Override the equals method in the Object class. Two Car objects are equal if their models are the same. 3. In the Car class override the wheels() method to display “A car has four wheels”. 4. A method named toString() that returns a string description for the car. 5. Override the HowToRun() method to display “A car runs with diesel”. Test class:
write a java programme:
Vehicle class:
First create an abstract Vehicle class that contains code common to all of the vehicles.
1. Vehicle class has a color, IDnumber, and a model.
2. Throw an exception named “InputNotCorrectException” if the IDnumber is negative.
3. The accessor and mutator methods for all three data fields.
4. Also include a void wheels() method which is declared abstract.
Runnable interface:
1.Deaclare an abstract method named HowToRun() which has a return type of void.
Car class:
Car class is a subclass of Vehicle which implements the Runnable interface.
1. Write a class called Car which extends the Vehicle class and implements the Runnable interface.
2. Override the equals method in the Object class. Two Car objects are equal if their models are the
same.
3. In the Car class override the wheels() method to display “A car has four wheels”.
4. A method named toString() that returns a string description for the car.
5. Override the HowToRun() method to display “A car runs with diesel”.
Test class:
1. Implement a test class to create an array of size x which can store both car objects where, x = the 5th digit of your University ID. For example, if your ID is 1238765999, then x
= 7.
2. Take parameters for the objects and invoke toString() and equals methods.
3. Write the information from previous step (point 3) to a file
