Program Plan Intro

Shape class:

  • The basic functionality for drawing shapes is included in “Shape” class.
  • A specific shape is been drawn by each of the subclasses in “Shape” class.
  • The “Shape” class is present in JavaFX library.
  • The lines are been drawn using “Line” class.
  • The circles are been drawn using “Circle” class.
  • The “Shape” class as well as its subclasses is present in “javafx.scene.shape” package.
  • The JavaFX library holds “Shape” class that provides features for drawing shapes.
  • The subclasses present in “Shape” includes:
    • Line:
      • It can draw a line from a point to another.
    • Circle:
      • It can draw a circle with a specific center as well as radius.
    • Rectangle:
      • It can draw a rectangle with specific height as well as width.
    • Ellipse:
      • It can draw an ellipse with a center point as well as radii.
    • Arc:
      • It draws an arc that denotes a partial ellipse.
    • Polygon:
      • It draws a polygon with vertices at particular locations.
    • Polyline:
      • It draws a polyline with vertices at particular locations.
    • Text:
      • It draws a string at a particular location.
  • The package used for “Shape” class as well as its subclasses is “javafx.scene.shape”.

Example:

The example for “Ellipse” class is given below:

Ellipse elp = new Ellipse(320, 240, 140, 100);

Here, “elp” denotes an object of “Ellipse” class. The given code generates an ellipse with given dimensions. The coordinates (140, 100) denotes X and Y coordinates respectively.

How do you draw a line with an arrowhead?
Calculating the area under a curve is a standard problem in numerical methods. What you will develop is an app that calculates and displays the area under a range of curves.   Figure 1: Area under the curve of y = x2 over the range 1 to 2, with 1 trapezoid.   The area can be calculated by drawing one or more polygons (trapezoids) that approximate the curve. We start by drawing a trapezoid that encompasses our curve between the given limits and the x-axis, so for equation 1 of table 1, it looks like figure 1. We then calculate the area of the trapezoid. Notice that the trapezoid over-estimates the true area. With enough (smaller) trapezoids we can get a very good approximation to the area under the curve (see figure 2). The sum of the area of the smaller trapezoids is the area under the curve. The area of a trapezoid is given by: A = ½ (h1 + h2) d Plot graphs of the equations in table 1 for varying (input) total numbers of trapezoids. Compute and display the area between each curve and…
