I'm lost on this one. Help is much appreciated. I've went over the book many times. It just doesn't explain this.

Code the following ADTs (classes), making sure to follow the instructions in the bulleted lists:

1. class namedEmployee
2. that has the following fields:
3. name
4. idNumber
5. department
6. position (job title)
7. and the following methods:
8. A no-argument constructor
9. A constructor that sets the data to passed values
10. Getters and setters for each piece of data
11. A toString( ) method to display the object data
12. Include Javadoc comments for the class and every method
13. Use a separate Java application to "unit test" this class by creating 3 objects.
14. Generate the Javadoc/API document for this ADT

1. class nameCar
2. that has the following fields:
3. yearModel (integer holding the car's year model)
4. make (String holding the make of the car)
5. speed (integer holding the car's current speed)
6. and the following methods:
7. A no-argument constructor
8. A constructor that sets the data to passed values
9. Getters and setters for each piece of data
10. accelerate: adds 5 to the speed field each time it is called
11. brake: subtracts 5 from the speed field each time it is called
12. A toString( ) method to display the object data
13. Include Javadoc comments for the class and every method
14. Use a separate Java application to "unit test" this class by creating 2 objects.
15. Generate the Javadoc/API document for this ADT
