Try It Yourself: Defining Instantiable Classes

Write the code for the instantiable class PlayingCard that represents a playing card. The following information is provided (i.e., this is the public interface). Comment any assumptions that you make.

`PlayingCard(String suitName, int faceValue)`	constructs a playing card with the given suit and value
`getSuit()`	returns the `String` suit of the card
`getFaceValue()`	returns the `int` face value of the card

Write the code for the instantiable class Circle that represents a circle in the xy plane. The following information is provided. For points, assume you have this simple Point class. Comment any assumptions that you make.

`Circle(Point centerPt, double r)`	constructs a circle with the given center point and radius
`getCenter()`	returns the `Point` center point of the circle
`getRadius()`	returns the `double` radius value of the circle
`setRadius(double newR)`	sets the radius to the value given
`setCenter(Point newCenter)`	sets the center point to the point given
`computeArea()`	returns the `double` area of the circle
`computeCircumference()`	returns the `double` circumference of the circle

Write the code for the instantiable class Rectangle that represents a rectangle in the xy plane. The following information is provided. For points, assume you have this simple Point class. Comment any assumptions that you make.

`Rectangle(Point upperLeftPt, double h, double w)`	constructs a rectangle with the given height h and width w whose upperleft corner is at the given point
`getUpperLeft()`	returns the `Point` upperleft corner point of the rectangle
`getHeight()`	returns the `double` height of the rectangle
`getWidth()`	returns the `double` width of the rectangle
`computeArea()`	returns the `double` area of the rectangle
`computePerimeter()`	returns the `double` perimeter of the rectangle
`scale(double factor)`	scales the dimensions of the rectangle by the given factor
`shift(Point p)`	shifts the upperleft corner of the rectangle to the point given
