Answer to Question #307722 in Java | JSP | JSF for Manoj

Question

Design a Car model class under package :package6 with the following attributes:

Member Field Name

Type

licenceNumber

String

Model

String

currentMileage

Double

engineSize

Intege

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

Design another class as Main under package :package6, where you need to implement logic as follows:

Declare an array as Car with size 10.

Take 10 Carà ƒ ¢ € ™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 current Mileage & engine Size

Current Mileage & engine Size values should be taken from Main class and pass to findCarList method as argument as well as Car array (with size 10).

Design findCarList method in Car class as follows
