详细说明： 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 ano ther 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 ...展开收缩
