Chapter 6, Problem 2PC
Car Class
Write a class named Car that has the following fields:
- yearModel. The yearModel field is an int that holds the car’s year model.
- make. The make field references a String object that holds the make of the car.
- speed. The speed field is an int that holds the car’s current speed.
In addition, the class should have the following constructor and other methods.
- Constructor. The constructor should accept the car’s year model and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field.
- Accessors. Appropriate accessor methods should get the values stored in an object’s yearModel, make, and speed fields.
- accelerate. The accelerate method should add 5 to the speed field each time it is called.
- brake. The brake method should subtract 5 from the speed field each time it is called.
Demonstrate the class in a program that creates a Car object, and then calls the accelerate method five times. After each call to the accelerate method, get the current speed of the car and display it. Then call the brake method five times. After each call to the brake method, get the current speed of the car and display it.

Write a class named Retailltem that holds data about an item in a retail store. The class should have the
following fields:
• description. It is a String object that holds a brief description of the item.
• unitsOnHand. It is an int variable that holds the number of units currently in inventory.
• price. It is a double that holds the item's retail price.
