Three Drawings (30 points)

Draw these shapes using section 2.10 in your text as your guide. Make sure the orientation of each (in the XY plane ) is as shown.

Chapter 3 explores import statements further A class that defines an applet extends the JApplet class, as indicated in the header line of the class declaration. This process is making use of the object oriented concept of inheritance, which we discussed in Chapter 1 and explore in more detail later in the book. Applet classes must also be declared as public. The paint method is one of several applet methods that have particular sig- nificance. It is invoked automatically whenever the graphic elements of the applet need to be painted to the screen, such as when the applet is first run or when another window that was covering it is moved Note that the paint method accepts a Graphics object as a parameter. A Graphics object defines a particular graphics context with which we can interact. The graphics context passed into an applet's paint method represents the entire applet window. Each graphics context has its own coordinate system. In later examples, we will have multiple components, each with its own graphics context. A Graphics object allows us to draw various shapes using methods such as drawRect, drawoval, drawLine, and drawstring. The parameters passed to the drawing methods specify the coordinates and sizes of the shapes to be drawn. We explore these and other methods that draw shapes in the next
