Description: Create 5 classes called MobileDevice, SmartPhone, Android, iPhone, WindowsPhone, with a private field deviceType that will be initialized to the string “Mobile Device in the constructor including the corresponding setter and getter methods. The program will shows the result as:
Mobile Device –> SmartPhone –> Android
Mobile Device –> SmartPhone –> iPhone
Mobile Device –> SmartPhone –> WindowsPhone
Code:
Main
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());
}
}
