Switch case for two INT variables

Question

Consider the following code :

if (xPoint > 0 && yPoint > 0) {
    m_navigations = Directions.SouthEast;
}
else if (xPoint > 0 && yP         


        

Answer 1

Similar to other answers but without strings. Just for fun :-)

public Directions getDirection(int xPoint, int yPoint) {
    int num = 8 * (xPoint == 0 ? 0 : xPoint > 0 ? 1 : 2);
    num += yPoint == 0 ? 0 : yPoint > 0 ? 1 : 2;
    switch (num) {
    case 01:
        return Directions.South;
    case 02:
        return Directions.North;
    case 010:
        return Directions.East;
    case 011:
        return Directions.SouthEast;
    case 012:
        return Directions.NorthEast;
    case 020:
        return Directions.West;
    case 021:
        return Directions.SouthWest;
    case 022:
        return Directions.NorthWest;
    }
    return Directions.None;
}
