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.

Example:

The example for a “Line” class constructor is given below:

Line(startX, startY, endX, endY)

Here, “startX” and “startY” denotes starting point’s “X” and “Y” coordinates. The “endX” and “endY” denotes ending point’s “X” and “Y” coordinates.

Package for Shape class:

• The JavaFX library holds “Shape” class that provides features for drawing shapes...
