Chapter 4, Problem 28PP

Program Plan Intro

Cubic curve

Program plan:

• Create a class “Cubic”,
  • Define the function “draw()”,
    • Create object for “Graphics2D” class.
    • Declare and initialize the necessary variables.
    • Set “x” as “x_min”.
    • Execute “for” loop till number of line segments.
      • Calculate “y” value.
      • Set the “x” and “y” coordinates to the next x and y values.
      • If the value of “i” is greater than “1”,
        • If the condition is true, set the Boolean value is “true”.
        • Create the 2D line.
        • Draw the line.
      • Update the “x” and “y” values.
• Import necessary packages.
• Create a class “CubicView”,
  • Define “main()” function,
    • Create an object for “JFrame” class.
    • Initialize the necessary variables.
    • Set the size, title, and close operation for the frame.
    • Define “JComponent” constructor.
      • Define “paintComponent()”,
        • Call the constructor “Cubic()” to create object.
        • Call “draw()” method to draw the cubic curve.
    • Add the component into the frame.
    • Make the frame visible.
