Description
FOR LAB #5 I IMPLEMENT SOME CHANGE FROM THE LAST LAB, WHO WAS ABOUT MOBILE DEVICES. IN THE PRECIOUS LAB 4 I USED 4 MOBILE DEVICES WHO WERE IPHONE, ANDROID,SMARTPHONE AND WINDOWPHONE. IN LAB 5 I DIDNT DO ANY CHANGE THE ONLY CHANGE I DID WAS JUST ADD TWO OTHER DEVICES IN ORDER OF HIERARCHY. THE IMPLEMENTATION THAT I DID WAS TO ADD TWO NEW MOBILE DEVICES WHICH WERE KINDLE FIRE AND NEXUS 7. WHEN I RUN THE PROGRAM TOGETHER WITH THE OTHER DEVICES FROM PREVIOUS LAB, I WAS ABLE TO SEE ALL THE COMPONENT LISTING TOGETHER AS ONE.

CODE
Part1 package lab4;

public class MobileDeviceApp {

public static void main(String[] args) {

MobileDevice[] mobileDevices = new MobileDevice[6];
mobileDevices[0] = new smartphone();
mobileDevices[1] = new Iphone5();
mobileDevices[2] = new androi();
mobileDevices[3] = new WindowsPhone();
mobileDevices[4] = new kindlefire();
mobileDevices[5] = new nexus7();

for (MobileDevice m: mobileDevices){
System.out.println(“This device is: ” + m.toString());
}
}

}

package lab4;

public abstract class MobileDevice {

public String deviceType = “Device Type”;

public abstract void setDeviceType();

public String getDeviceType(){

return this.deviceType;

}

}
