The objective of this lab is to write a Java program that use inheritance. Inheritance is when a subclass is derived from a superclass. it is the same as the concept of inheritance from one family member to another.
Code:
Lab4;
public class MobileDevice {
private String deviceType;
public MobileDevice() {
deviceType = "Mobile Device";
// TODO Auto-generated constructor stub
}
public String getDeviceType() {
return deviceType;
}
public void setDeviceType(String deviceType) {
this.deviceType = deviceType;
}
}
Lab4;
public class SmartPhone extends MobileDevice {
private String deviceType;
public SmartPhone() {
deviceType = "SmartPhone";
// TODO Auto-generated constructor stub
}
public String getDeviceType() {
return deviceType;
}
public void setDeviceType(String deviceType) {
this.deviceType = deviceType;
}
}
Lab4;
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());
}
}
Lab4;
public class iPhone extends SmartPhone{
public iPhone () {
}
@Override
public String getDeviceType() {
return deviceType = "Mobile Device -> Smart Phone -> IPhone";
}
}
Lab4;
public class Android extends SmartPhone {
public Android() {
}
@Override
public String getDeviceType () {
return deviceType = "Mobile Device -> Smart Phone -> Android";
}
}
Lab4;
public class WindowsPhone extends SmartPhone {
public WindowsPhone() {
}
@Override
public String getDeviceType() {
return deviceType = "Mobile Device -> Smart Phone -> Windows Phone";
}
}
