Answer 29

True

Back to Question 29

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 24

False. An object of type Ellipse2D.Double represents an ellipse that is bounded by the four sides of a rectangle. If the rectangle is square, theellipse becomes a circle .

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

Back to Question 19

Answer 18

False. A call to the draw method of the GM2D02.Line class causes an object of the standard Java Line2D.Double class to be rendered onto the specified graphics context.

A. An underlying data object

Back to Question 7

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.

Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
