In this program, we will java Program see how to calculate the area of a circle when the radius is given.
编写一个完整的Java Application 程序。包含接口ShapeArea,类Circle、Rectangle、Test,具体要求如下:⑴接口ShapeArea:
(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,...
private static double volume(String solidom, double alturam, double areaBasem, double raiom) {double vol; if (solidom.equalsIgnoreCase("esfera"){ vol=(4.0/3)*Math.pi*Math.pow(raiom,3); } else { if (solidom.equalsIgnoreCase("cilindro") { vol=Math.pi*Math.pow(raiom,2)*alturam; }...
public class Circle{ private double radius; public CircleR(double r) public diameter() { double d = radius * 2; return d;}} 有若干途径会触发“Invalid Method Declaration; Return Type Required” 错误: 忘记声明类型 如果方法没有返回值,那么需要将“void”声明为方法签名中的类型。
