Program Plan Intro

Monkey face and hand in JavaFX Application

Program Plan:

• • Import required package.
• • Define “enum” class for monkey hand position.
• • Define “drawMonkeyFace” class.
  • ○ Initializes required variables.
  • ○ Define main function.
  • ○ Define “drawFace” method with argument of “GraphicsContext” object, “at_XBase”, “at_YBase” and “HandPosition” object.
    • ■ Invoke “strokeOval” method for object “gContext”.
    • ■ Compute the monkey ear width, height and offset to draw the monkey ear.
    • ■ Invoke “strokeOval” method for object “gContext”.
    • ■ Compute the monkey eye width, height and offset to draw the monkey eye.
    • ■ Invoke “strokeOval” method for object “gContext”.
    • ■ Compute the monkey mouth width, height and offset to draw the monkey mouth.
    • ■ Invoke “strokeArc” for object “gContext” which is used to draw arc.
    • ■ Declare required variables for hand offset.
    • ■ Check location of hand using “switch” case.
      • • If the case is “MONKEY_MOUTH”, then compute hand offset for “X” and “Y” and then call “drawMonkeyHand” method.
      • • If the case is “MONKEY_EYE”, then compute hand offset for “X” and “Y” and then call “drawMonkeyHand” method.
      • • If the case is “MONKEY_EAR”, then compute hand offset for “X” and “Y” and then call “drawMonkeyHand” method.
  • ○ Define “drawMonkeyHand” method with argument of “GraphicsContext” object, “at_XBase” and “at_YBase”.
    • ■ Compute palm width and height.
    • ■ Invoke “fillOval” method for object “gContext”.
    • ■ Compute finger width, height of monkey and offset.
    • ■ Invoke “fillOval” method for object “gContext”.
  • ○ Define “start” method.
    • ■ Create an object “rt” from “Group” class.
    • ■ Create an object “s” from “Scene” class.
    • ■ Create an object “ca” from “Canvas” class.
    • ■ Create object for “GraphicsContext” class.
    • ■ Draw monkey ear by calling method “drawFace”.
    • ■ Set the font by using the method “setFont”.
    • ■ Set text for first monkey face by using method “fillText”.
    • ■ Draw monkey eye by calling method “drawFace”.
    • ■ Set text for second monkey face by using method “fillText”.
    • ■ Draw monkey mouth by calling method “drawFace”.
    • ■ Set text for third monkey face by using method “fillText”.
    • ■ Set title for given program.
    • ■ Call “setScene” method for stage.
    • ■ Display the all pics by using method “show”.
