Given the following Java classes.

public abstract class Shape {

protected String name;

public Shape( String n ) {

name = n;

}

public abstract double getArea();

public String getName() { return name; }

}

public class Point {

private double x, y;

public Point( double a, double b ) { setPoint( a, b ); }

public void setPoint( double a, double b ) {

x = a;

y = b;

}

public double getX() { return x; }

public double getY() { return y; }

public String toString() {

return "[" + x + ", " + y + "]";

}

}

Shown below is a tentative program for testing Shape and its subclasses.

public class TestShape {

public static void main( String [] args ) {

Shape[] myShapes = new Shape[3];

myShapes[0] = new Circle( 10.5, 20, 25 );

myShapes[1] = new Rectangle( 30.5, 23.5, 15.5, 20.5 );

myShapes[2] = new Circle( 8, 9.5, 10.5 );

for ( int i = 0; i < myShapes.length; i++ ) {

System.out.println(myShapes[i].getName() + "="

+ myShapes[i].toString() + "; Area="

+ myShapes[i].getArea() );

}

}

}

Write a class Circle which inherits from Shape. The additional variables of Circle are shown below.

Variable name	Data type
radius	double
center	Point

The additional methods of Circle are shown below.

Method name	Description	Inputs	Output
Circle()	Constructor. It accepts 3 double numbers and assigns them to the radius, x, and y coordinates of the center, respectively. It also sets the name as circle by calling an appropriate constructor in the superclass.	3 double values	none
getRadius()	Returns the value of the radius variable.	none	a double value
getCenter()	Returns the center Point of the circle.	none	a Point object
setRadius()	Set the radius variable to the value of the input parameter.	a double value	none
setCenter()	Set the center variable to the Point passed as input parameter.	a Point object	none
getArea()	Returns the area of the circle.	none	a double value
toString()	Returns a description of the circle.	none	a String
