Chapter 14, Problem 5PC

Program Plan Intro

Program plan:

• Include necessary header files.
• Define a class “PolygonApplet”.
  • Declare and initialize the necessary variables.
  • Define a method “init()”.
    • Call the necessary methods to initialize the polygon.
  • Define a method “paint()”.
    • Call the method “setcolor()” using the graphics object “g”.
    • Call the method “drawRect()”using the graphics object “g”.
  • Define a method “line()”.
    • Call the method “getGraphics()” and assign the result into the object “g”.
    • Call the method “drawLine()” using the object “g”.
    • Call the method “dispose()” using the object “g”.
  • Define a method “polygon()”.
    • The “if” loop to check “count” is less than “2”.
      • True, return the value.
    • Call the method “getGraphics()” and assign the result into the object “g”.
    • The “if” loop to check “count” is equal to “2”.
      • True, call the method “drawLine()” using the object “g”.
    • Otherwise, call the necessary methods using the object “g” to draw a polygon.
  • Define a method “mousePressed()” to draw a polygon.
  • Define a method “mouseReleased()”.
  • Define a method “mouseClicked()”.
  • Define a method “mouseEntered()”.
  • Define a method “mouseExited()”.
