用JAVA编写程序，输入半径和高，通过圆柱的底面积公式和体积公式来计算圆柱的底面积和体积！
eg:
代码：
import java.util.Scanner;
public class bb{
public static void main(String[] args){
final double PI = 3.14159;
System.out.print("please input radius and height:");
Scanner input = new Scanner(System.in);
double radius = input.nextDouble();
double height = input.nextDouble();
double area = PI * radius * radius;
double volumn = area * height;
System.out.println("The area is "+area);
System.out.println("The volumn is "+volumn);
}
}
结果:
