For passing the the object:

Bundle bundle = new Bundle();
ArrayList <Car> CarList = new ArrayList<Car>();  
Car carItems= new Car(carno, cartype, date, arriveTime, carcost);   
CarList.add(carItems); 
bundle.putSerializable("carList",carList);
intent.putExtras(bundle);

For retrieving:

ArrayList <Car> CarList = getIntent().getSerializableExtra("carList");

Make sure Car is serializable:

public class Car implements Serializable {

}

It show error as The method putExtra(String, boolean) in the type Intent is not applicable for the arguments (String, List) – user2799407 Mar 14 '14 at 10:19
Have you made your `Car` class implement [Parcelable](http://developer.android.com/reference/android/os/Parcelable.html) – betteroutthanin Mar 14 '14 at 10:23
public class Car implements Parcelable and I bave implemented public int describeContents(), public void writeToParcel(Parcel dest, int flags) – user2799407 Mar 14 '14 at 10:25

Make it parcleable, pretty easy.

Have a look on this posting: Arraylist in parcelable object

An ArrayList full of Objects can be put into any parcel using: http://developer.android.com/reference/android/os/Parcel.html#writeTypedList(java.util.List) – Kitesurfer Mar 14 '14 at 10:29

It seems that you actually have to make Car a Parcelable.

To add it to the Intent, use putParcelableArrayListExtra(String name, ArrayList<? extends Parcelable> value)

Edit

To get the list in the other activity, do this in onCreate or onNewIntent:

Intent i = getIntent();
ArrayList<Car> cars = i.getParcelableArrayListExtra("extraKeyUsedWithPutExtra");
