    Creating Two Business Objects... Do these have all of the methods/functions needed?

    Hey everyone... I'm creating some business objects for a class I'm taking to freshen up on my skills, and I have had to make a few business objects. I'm pretty sure on the others (the other ones are testing my thoroughness on interfaces, abstract classes, and inheritance). I just have to write methods that deal with the functionality related to these two objects (the code doesn't have to be perfect at all, pseudo code is acceptable):

    1) Building Object (say the building is 20 levels, but this could work for any building with a number of floors)

    2) Elevator Object (has to include code to include the machinery moving the elevator up and down smoothly, not just going from level 1 to level 3, etc... it has to pass from level 1 to level 2 to level 3)

    ** I definitely need help and making sure I am going in the right direction... any help is APPRECIATED!!!

    class Building
    {
    boolean _bPower = false;
    int _iNumberOfFloors = 0;

    public void setPower(boolean b) { _bPower = b;}
    public boolean hasPower() { return _bPower; }

    public void setNumberOfFloors(int i) { _iNumberOfFloors = i;}
    public int getNumberOfFloors() { return _iNumberOfFloors; }


    }

    class Elevator
    {
    boolean _bWorking = false;
    boolean _bDoorOpened = true;
    boolean _bButtonDepressed = false;
    Vector _vFloorCalledQuery = new Vector();
    int _iCurrentFloor = 0;

    public void setElevatorWorking(boolean b) { _bWorking = b; }
    public boolean isWorking() { return _bWorking); }

    public void setDoorOpened(boolean b) { _bDoorOpened = b; }
    public boolean isDoorOpened() { retrun _bDoorOpened; }

    public void setButtonDepressed(boolean b) { _bButtonDepressed = b; }
    public boolean isButtonDepressed() { retrun _bButtonDepressed ; }

    public void setFloorCalledQuery(int i)
    {
    boolean bAlreadyInQue = false;

    for (int j = 0; j < _vFloorCalledQuery.size(); j++)
    {
    if (_vFloorCalledQuery.elementAt(j) == i)
    {
    bAlreadyInQue = true;
    }

    if (!bAlreadyInQue)
    {
    _vFloorCalledQuery.add(i);
    // How do I sort this integer vector so the elements are in a proper order?
    }


    }


    } // adds to which floor is called

    public Vector getFloorCalledQuery() { return _vFloorCalledQuery ; } //returns a Vector of floors called in que


    public void moveElevator(int iNumberOfFloors, int iCurrentFloorFromPressedButton )
    {
    boolean bDirectionOfElevator = true; // true means elevator going up, false means elevator going down
    boolean bReachedElevatorFloor = false;

    if (_bWorking )
    {
    if (_bDoorOpened)
    {
    _bDoorOpened = false; //close the door
    }

    if (_iCurrentFloor == iCurrentFloorFromPressedButton)
    {
    _bDoorOpened = true; //open the door, it's the same floor
    }
    else
    {
    if (iCurrentFloorFromPressedButton - _iCurrentFloor > 0)
    {
    // elevator is moving upwards
    bDirectionOfElevator = true;
    for (int i=_iCurrentFloor; i< iNumberOfFloors; i++)
    {
    if (_iCurrentFloor == iCurrentFloorFromPressedButton )
    {
    // reached floor
    while (!bReachedElevatorFloor)
    {
    // haven't reached floor, need to check the next floor and then see if that floor is in the que
    if (_vFloorCalledQuery.size() > 0)
    {
    for (int k=0; k < _vFloorCalledQuery.size(); k++)
    {
    if(_iCurrentFloor == _vFloorCalledQuery.elementAt(k))
    {
    _bDoorOpened = true;
    // HOW DO I ADD ANOTHER POSITION to the que??
    }
    }

    }

    }
    }
    bReachedElevatorFloor = true;
    break;


    }
    }
    else
    {
    // elevator is moving downwards

    }

    }



    }
    }


    }
