Create a class called Circle.java with fields named radius, area, and diameter. Include methods named setRadius(), getRadius, and computeDiameter(), which calculates the circle's diameter, and computeArea(), which computes the circle's area. Hint: diameter of a circle is twice its radius. Hint: area of a circle is 3.14 multiplied by the square of the radius. Create a class called TestCircle. java whose main method declares 2 Circle objects. Using setRadius() method, assign one Circle a small radius value and assign another a larger radius value. Call computeDiameter() and computeArea for each circle and display the results. Output result of using command input "5 8": The area of a is 78.5 The diameter of a is 10.0 The area of b is 200.96 The diameter of b is 16.0

好的，我很乐意为您介绍Shape及其子类Oval。Shape是一个抽象类，它代表着一个形状，它具有许多属性，比如颜色、填充等，但它本身并不表示任何形状。它的子类Oval代表着一个椭圆形，它继承了Shape的所有属性，并且包含一些自己的属性，比如长轴、短轴等。如果您想设计更多的形状，可以考虑创建Shape的其他子类，比如Circle或Rectangle等，它们都可以继承Shape的属性并添加自己的属性。至于具体的实现和代码细节，需要视具体的编程语言和程序需求而定。
