1. Design and implement a TimeDate ADT that can be used to represent both a date and time as a single entity.

2. A line segment is a straight line bounded by two endpoints. The Line Segment ADT, whose operations are described below, represents a line segment defined by points in the two-dimensional Cartesian coordinate system. Use the Point class from Appendix D and implement the Line Segment ADT.

* LineSegment( ptA, ptB ): Creates a new Line Segment instance defined by the two Point objects.
* endPointA(): Returns the first endpoint of the line.

* endPointB(): Returns the second endpoint of the line.

* length (): Returns the length of the line segment given as the Euclidean distance between the two endpoints.

* toString (): Returns a string representation of the line segment in the format (Ax, Ay)#(Bx, By).

* isVertical(): Is the line segment parallel to the y-axis?

* isHorizontal(): Is the line segment parallel to the x-axis?

* isParallel( otherLine ): Is this line segment parallel to the otherLine?

* isPerpendicular( otherLine ): Is this line segment perpendicular to the otherLine?

* intersects(otherLine ): Does this line segment intersect the otherLine?

* bisects( otherLine ): Does this line segment bisect the otherLine?

* slope(): Returns the slope of the line segment given as the rise over the run. If the line segment is vertical, None is returned.

* shift( xInc, yInc ): Shifts the line segment by xInc amount along the x-axis and yInc amount along the y-axis.

* midpoint(): Returns the midpoint of the line segment as a Point object.
