The objective of the lab is to learn how to program android application using java.eclipse (Android SDK)
Lab6
This lab is basically create a program that will polymorphically process an array of Movable by calling each of the interface methods.
Code:
package Lab6;
public class Car implements Movable {
@Override
public void moveForward() {
System.out.println(“Car drives forward”);
}
@Override
public void movebackward() {
System.out.println(“Car drives backward”);
}
@Override
public void stop() {
System.out.println(“Car parked”);
}
@Override
public void moveleft() {
System.out.println(“Car turns left”);
}
@Override
public void moveright() {
System.out.println(“Car turns right”);
}
@Override
public void moveBackward() {
}
@Override
public void moveLeft() {
}
@Override
public void moveRight() {
}
}
package Lab6;
public interface Movable {
public void moveForward();
public void moveBackward();
public void stop();
public void moveLeft();
public void moveRight();
void moveright();
void moveleft();
void movebackward();
}
package Lab6;
public class MovableApp {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Movable[] myMovables = new Movable[3];
myMovables[0] = new Plane();
myMovables[1] = new Car();
myMovables[2] = new Ship();
for (Movable m: myMovables){
m.moveForward();
m.movebackward();
m.stop();
m.moveleft();
m.moveright();
System.out.println(“————————-“);
}
}
}
package Lab6;
public class Plane implements Movable {
@Override
public void moveForward() {
System.out.println(“Plane flying forward”);
}
@Override
public void movebackward() {
System.out.println(“Plane taxiing backward”);
}
@Override
public void stop() {
System.out.println(“Plane landen”);
}
@Override
public void moveleft() {
System.out.println(“Plane flying left”);
}
@Override
public void moveright() {
System.out.println(“Plane flying right”);
}
@Override
public void moveBackward() {
}
@Override
public void moveLeft() {
}
@Override
public void moveRight() {
}
}
package Lab6;
public class Ship implements Movable {
@Override
public void moveForward() {
System.out.println(“Ship navigates forward”);
}
@Override
public void movebackward() {
System.out.println(“Ship navigates backward”);
}
@Override
public void stop() {
System.out.println(“Ship docked”);
}
@Override
public void moveleft() {
System.out.println(“Ship navigates left”);
}
@Override
public void moveright() {
System.out.println(“Ship navigates right”);
}
@Override
public void moveBackward() {
}
@Override
public void moveLeft() {
}
@Override
public void moveRight() {
}
}

The objective of this lab is to learn about inheritance in Java as well as the proper usage of abstract classes and methods. The program has to be able to follow the hierarchy below through the use of inheritance.
Code
package v2;
public class Android extends SmartPhone{
private String deviceType;
public Android(){
deviceType="Android";
}
public void setDeviceType(String value){
deviceType=value;
}
@Override
public String getDeviceType(){
return super.getDeviceType()+"->"+deviceType;
}
}
package v2;
public class iPhone extends SmartPhone{
private String deviceType;
public iPhone(){
deviceType="iPhone";
}
public void setDeviceType(String value){
deviceType=value;
}
@Override
public String getDeviceType(){
return super.getDeviceType()+"->"+deviceType;
}
}
package v2;
public class MobileDevice{
public String deviceType;
public MobileDevice(){
deviceType="Mobile Device";
}
public void setDeviceType(String value){
deviceType=value;
}
public String getDeviceType(){
return deviceType;
}
}
package v2;
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();
myWindowsPhone.setDeviceType("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());
}
}
package v2;
public class SmartPhone extends MobileDevice{
private String deviceType;
public SmartPhone(){
deviceType="Smart Phone";
}
public void setDeviceType(String value){

}
@Override

}
}
package v2;

}
public void setDeviceType(String value){
