求圆的面积【Java】

package myJava1;
public class circletest
{
public static void main(String[] args)
{
circle r;
r=new circle();
System.out.println("圆的半径是："+r.radious);
double result=r.area();
System.out.println("圆的面积是："+result);

} 
}
class circle
{
 int radious=10;
 double area()
 {
double PI=3.14;
return PI*radious*radious;
 }
}
