//Java Program to find the area of a circle given the radius import java.util.Scanner; class AreaOfCircle { double area; void circle(double rad) { area= (22*rad*rad)/7; } } public class Main extends AreaOfCircle
(1)定义一个Circle类,包含一个double型的radius属性代表圆的半径,一个findArea()方法返回圆的面积。 (2)定义一个类PassObject,在类中定义一个方法printAreas(),该方法的定义如下:publicvoidprintAreas(Cirlce c,inttimes) 在printAreas方法中打印输出1到time之间的每个整数半径值,以及对应的面积。例如,times为5,...

5.Write a Java program to create a class called Circle with a private instance variable radius. Provide public getter and setter methods to access and modify the radius variable. However, provide two methods called calculateArea() and calculatePerimeter() that return the calculated area and perime...
