Activity 1 ?MyCircle and MySquare extensions of MyShape A class has been defined called MyShape. This class has the following variables and methods: | | class MyShape | | | Variables | Methods | Public | int xPos | | Public | int yPos | | Public | | MyShape() | Public | | void setX( int newX ) | Public | | void setY( int newY ) |
See the listing of MyShape.java. Look at this listing for ShapeApplet.java: import java.applet.Applet;
import java.awt.*;
public class ShapeApplet extends Applet
{
MyCircle shape1;
MySquare shape2; public void paint( Graphics g )
{
shape1 = new MyCircle();
shape1.setX(100);
shape1.draw( g );
shape2 = new MySquare();
shape2.setY(20);
shape2.draw( g );
}
} You need to define 2 new classes, called MyCircle and MyClass that both are direct subclasses of MyShape . Each class should have a constructor method (setting initial values to appropriate instance variable such as radius for the circle and sideLenth for the square), and should also define a draw( Garphics g ) method that makes use of the inherited xPos and yPos instance variables. You can use the file Shape.html to load the applet into the appletviewer. Discussion/Suggested solution to Activity 1
