cylindertest.java

（1） 编写一个代表圆柱体的Cylinder类

import p2.Point;
public class CylinderTest
{
	public static void main(String agrs[])
	{
		Cylinder cy1=new Cylinder(5,8,8,9);
		Point p=new Point(3,4);
		Cylinder cy2=new Cylinder(p,6,7);
		Cylinder cy3=new Cylinder();
        System.out.println("The volume of the Cylinder(p(3,4),6,7) is: "+cy2.volume());
		System.out.println("The volume of the Cylinder() is: "+cy3.volume());
		System.out.println("The surfaceArea of the Cylinder(p(3,4),6,7)is :"+cy2.surfaceArea());
		System.out.println("The surfaceArea of the Cylinder()is :"+cy3.surfaceArea());
		System.out.println(cy1.toString());
		System.out.println(cy2.toString());
		
	}
}
