LAB DESCRIPTION:

Instructions:

1-      Create a class called MobileDevice with a private field deviceType that will be initialized to the string “Mobile Device” in the constructor. Include the corresponding setter and getter methods.

2-      Create another class SmartPhone that will inherit MobileDevice, with a private field deviceType initialized to the string “Smart Phone” in the constructor, and override the getter method by returning the string:

“Mobile Device -> Smart Phone”. (Hint: To obtain this result make a call to the super class getter method).

3-      Create three more classes: Android, iPhone, and WindowsPhone that will inherit SmartPhone, have a private field deviceType initialized to the string “Android”, “iPhone”, or “Windows Phones” correspondingly in the constructor, and override the getter method returning the corresponding string

“Mobile Device -> Smart Phone -> iPhone” for iPhone,

“Mobile Device -> Smart Phone -> Android” for Android”, or

“Mobile Device -> Smart Phone -> Windows Phone” for Windows Phone.

CODE:

public class MobileDevice {

	private String deviceType;

	public MobileDevice(){

		deviceType = "Mobile Device";

	}

	public void setDeviceType(){

	}

	public String getDeviceType(){

		return deviceType;
	}

	/**
	 * @param args
	 */

}
