Question

Is it possible for me to hold all my private datatype within my abstract class so i can later use the stored information to be held within my array List (array list is in a different class). I have managed to store all Strings previously bur had no success with my Boolean value. I know that array lists are used to reference objects. Thanks

public abstract class Room
{
    private String roomID;
    private boolean ensuite;
    private String guest;
    private String nights;
    private String booked;

    public abstract room (String roomID boolean ensuite)
}

Answer 1

Has this been copied exactly from your code? there is a , missing between String roomId and boolean ensuite. Also abstract is not needed in the method declaration.

Try this:

public abstract class Room
{
    private String roomID;
    private boolean ensuite;
    private String guest;
    private String nights;
    private String booked;

    public Room (String roomID, boolean ensuite)
    {
       this.roomID = roomID;
       this.ensuite = ensuite;
       //so on...
    }
}
