Answer 29

True

Answer 28

True. One example is the graphical addition of vectors using the tail-to-head placement.

Back to Question 28

Answer 27

True, because according to Kjell, a vector doesn't have a position. Hence, there is nothing in the underlying data for a GM2D02.Vector object that specifies a position.

Back to Question 27

Answer 26

False. The draw method of the GM2D02.Vector class requires two parameters:

  • A reference to the off-screen graphics context
    • on which the visual manifestation of the vector will be drawn.
  • A reference to an object of the class GM2D02.Point
    • that will be used to determine the position on the off-screen image in which the visual manifestation will appear.

Answer 21

False. One of the hallmarks of object-oriented programming is that objects do know how to do useful things for themselves.

Back to Question 21

Answer 20

False. The Line2D.Double class is a member of the standard Java library, whereas the GM2D02.Line class is a member of the special game math library named GM2D02 .

Answer 19

True

Answer 6

False. GM2D02.Vector objects represent themselves as lines with small circles at their heads in a graphics context for the benefit of humanobservers.

Back to Question 6

Answer 5

False. GM2D02.Point objects represent themselves as small black circles in a graphics context for the benefit of human observers.

Back to Question 5

Answer 4

True

Back to Question 4

Answer 3

False. A point is simply a location in space. It has no width, depth, or height. Therefore, it cannot be seen by the human eye, which means that we can'tdraw a point on the computer screen. However, it is possible to draw an object on the computer screen that indicates the location of the point.

Back to Question 3

Answer 2

False. Points in space exist regardless of whether or not visual objects are created to mark the locations of the points.
