编写一个程序,要求输入圆的半径,求圆的周长,面积.并输出结果.PS:本人是已经测试过了importjavax.swing.JOptionPane;classaccount{public
importjava.util.Scanner;publicclassTest{publicstaticvoidmain(Stringagrs[]){Scannera=newScanner(Syste
本人初学,答的不好的地方请见谅,程序代码如下:importjavax.swing.JOptionPane;publicclassyuan{publicstaticvoidmain(Stringargs
voidmain(){floatr,s,l;floatpi=3.1415;printf("输入一个圆的半径:\n");scanf("%f",&r);if(
function[SV]=sphere(R)%定义函数S=pi*R^2;%求圆的面积V=4/3*pi*R^3;%求求的体积调用方法[ab]=sphere(1)
楼上的方法应该没错,可感觉对于表现java面向对象的特性没有表现出来,下面是我写的,应该非常清楚明了了importjava.io.BufferedReader;importjava.io.InputS
