could you help with me finishing those class./?

@Override

// rectangle and the width and height

g.drawOval(widthValue,y,w,h);

Programming Project 3 The third programming project involves writing a program that draws two types of shapes, ovals and rectangles. This program consists of six classes. The first class is the Shape class, which is an abstract class that extends the predened Java class Rectangle. It should contain two instance variables, the color of the shape and whether the shape is solid or hollow. It should also contain a class (static) variable that keeps track of how many shapes have been created. It should have three instance methods. one class method and one abstract method: l. A constructor that accepts three parameters for the purpose of mi lizing the characteristics of the shape, a Rectangle object that denes the dimensions and position of the shape, the color of the shape and whether the shape is solid or hollow. It should also update the number of shapes created so far. 2. An instance method named seccolor that accepts the Graphics object as a parameter and sets the color for the next draw operation to the color of the current shape. 3. An instance method named gersol id that returns whether the shape is solid or hollow. A class method named geruoofsnapes that returns the number of shapes created so far. 5. An abstract method named draw that accepts a Graphics object as a parameter. .5 The shape class has two subclasses. The rst is oval. It should have the following two methods: 1. A constructor that accepts three parameters for the purpose of initializing the characteristics of the shape, a Rectangle object that denes the dimensions and position of the shape, the color of the shape and whether the shape is solid or hollow. 2. An overridden method draw that draws the oval object on the Graphics object passed as a parameter. The second subclass is Rectangular. It should have the following two methods: 1. A constructor that accepts three parameters for the purpose of initializing the characteristics of the shape, a Rectangle object that denes the dimensions and position of the shape, the color of the shape and whether the shape is solid or hollow. 2. An overridden method draw that draws the Rectangular object on the Graphics object passed as a parameter. The fourth class is named Drawing, which should extend the predefined Java class JPanel. It has one instance variable that contains the shape that is currently drawn. It should have three methods: 1. An overridden paintcomponent method that draws the current shape on the Graphics object that is passed to it as a parameter. It should also draw the number of shapes that have been created thus far in the upper left comer. 2. An overridden getPreferredSize method that species the dimensions of the drawing panel as 200 pixels wide and 200 pixels high. 3. An instance method named drawshape that is passed the current shape to be drawn. It first checks whether the shape provided will completely fit within the panel. If not, it throws an oucsidesounds exception. Otherwise. it saves the shape in the corresponding instance variable. It then calls repaint to cause that shape to be drawn. No additional public methods should be included in any of the above classes. The flh class named oursmelsonnds should dene a checked exception. The sixth class named projects should contain the main method. It should generate the GUI shown below: m Geometric Drlwlng D X sir-no type Fl TV! 00hr The combo-box for the shape type should allow two choices, either Rectangle or Ovalr The combo-box for the fill type should also allow two choices, either Hallow or Solid. The combo- box for the color should allow seven choices. Black, Red. Orange, Yellow, Green. Blue or Magenta. Clicking the Draw button should rst check Whether any non integer values have been entered in any of the fields that require integers. If so, an error message should be displayed in a JoptionPane window. Otherwise an appropriate shape object should be created and passed to the drawshape method of the Drawing class. If that call results in an OutsideEounds exception being thrown, an appropriate error message should be displayed in a JOptionpane window. Be sure to follow good proyamming style. which means making all instance variables private. naming all constants and avoiding the duplication of code. Furthermore you must select enough dinerent kinds of shapes to completely test the program
