Lab Description:

For this lab, I had to use Eclipse to create a script where classes will inherit other classes. For my inheritance tree, I started with the Superclass MobileDevice and another Superclass SmartPhone under MobileDevice.  then I added three Subclasses to the Superclass SmartPhone to finish my hierarchy tree.

Code:

class MobileDevice {
	private String deviceType = "Mobile Device";
	public String getDeviceType() {
		return deviceType;
	}
	public void setDeviceType(String MobileDevice) {
		this.deviceType = MobileDevice;
	}
}

class SmartPhone extends MobileDevice {
	private String deviceType = "Mobile Device -> Smart Phone"; 
	public String getDeviceType() {
		return deviceType;
	}
	public void setDeviceType(String deviceType) {
		this.deviceType = deviceType;
	}
}

class Android extends SmartPhone{
	private String deviceType = "Mobile Device -> Smart Phone -> Android"; 
	public String getDeviceType() {
		return deviceType;
	}
	public void setDeviceType(String deviceType) {
		this.deviceType = deviceType;
	}
}

class iPhone extends SmartPhone{
	private String deviceType = "Mobile Device -> Smart Phone -> iPhone"; 
	public String getDeviceType() {
		return deviceType;
	}
	public void setDeviceType(String deviceType) {
		this.deviceType = deviceType;
	}
}

class WindowsPhone extends SmartPhone{
	private String deviceType = "Mobile Device -> Smart Phone -> WindowsPhone"; 
	public String getDeviceType() {
		return deviceType;
	}
	public void setDeviceType(String deviceType) {
		this.deviceType = deviceType;
	}
}

public class MobileDeviceClient {	
	public static void main(String[] args) {

		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());
	}
}
