In this lab we create several classes describing mobile devices types. the first class was a private string . The second class is an inherit the first class which is Mobile device. then we had to create three more classes that will inherit the second class. this lab was a bit challenging but with the help of my group we were able to figure it out and get the program to run.

package edu.cuny.citytech.CET3640.Lab3;

public class MobileDevice extends Object {
	
	private String deviceType;

	public MobileDevice()
	{

		deviceType = "Mobile Device";
	}

	public void setDeviceType(String deviceType) 
	{
		this.deviceType = deviceType;
	}

	public String getDeviceType() {
		return deviceType;
	}


}

package edu.cuny.citytech.CET3640.Lab3;

public class SmartPhone extends MobileDevice {

	private String deviceType;

	public SmartPhone()
	{

		deviceType = "Smart Phone";
	}



	public String getDeviceType() 
	{
		return String.format("Mobile Device" + " -----> " + deviceType);
	}

}

package edu.cuny.citytech.CET3640.Lab3;


public class iPhone extends SmartPhone {

	private String deviceType;

	public iPhone()
	{

		deviceType = "iPhone";
	}


	public String getDeviceType() {

		return String.format("Mobile Device" + " -----> " + "Smart Phone" + " -----> " + deviceType);
	}

}

package edu.cuny.citytech.CET3640.Lab3;

public class Android extends SmartPhone{

	private String deviceType;

	public Android()
	{

		deviceType = "Android";
	}


	public String getDeviceType() {

		return String.format("Mobile Device" + " -----> " + "Smart Phone" + " -----> " + deviceType);
	}

}
package edu.cuny.citytech.CET3640.Lab3;

public class WindowsPhone extends SmartPhone {

	private String deviceType;

	public WindowsPhone()
	{

		deviceType = "Windows Phone";
	}


	public String getDeviceType() {
		return String.format("Mobile Device" + " -----> " + "Smart Phone" + " -----> " + deviceType);
	}

}

package edu.cuny.citytech.CET3640.Lab3;

public class MobileDeviceClient {

	public static void main(String[] args) {
		// TODO Auto-generated method stub

		MobileDevice myMobileDevice = new MobileDevice();
		SmartPhone mySmartPhone = new SmartPhone();
		iPhone myiPhone = new iPhone();
		Android myAndroid = new Android();
		WindowsPhone myWindowsPhone = new WindowsPhone();
		System.out.println(myMobileDevice.getDeviceType());
		System.out.println(mySmartPhone.getDeviceType());
		System.out.println(myiPhone.getDeviceType());		
		System.out.println(myAndroid.getDeviceType());
		System.out.println(myWindowsPhone.getDeviceType());

	}
