Answer to Question #309709 in Java | JSP | JSF for Sowmya

Question

Design aCar model classunder package :package4 with the following attributes:

Member Field Name

Type

licenceNumber

String

Model

String

currentMileage

Double

engineSize

Integer

Mark all the attributes as private & create appropriate Getters & Setters

Design another class as Mainunder package :package4, where you need to implement logic as follows:

Declare an array as Car with size 10.

Take 10 Car's information from user and store them in specified array.

Call findCarList method from Main class to get all cars information related to a given model name and display then within this method.

Model name should be taken from Main class and pass to find CarList method as argument as well as Car array (with size 10).

Design findCarList method in Car classas follows:

• it will take a model(car model) as parameter and array of cars (with size 10)

• displays List of cars for the given model from the list.

• If there are no cars, then shows "No cars found".
