Hi friend,


I am sending running code. I hope, This code will help you.


import java.io.*;

public class RadiusCircleDemo{
public static void main(String[] args){
int r=0;
int s=0;
try{
BufferedReader buff = new BufferedReader(new InputStreamReader(System.in));
String str="y";
while(str.equals("Y")||str.equals("y")){
System.out.println("Enter Radius of Circle : ");
r = Integer.parseInt(buff.readLine());
double area = java.lang.Math.PI*r*r;
System.out.println("Area of Circle : "+area);
double perimeter =2*java.lang.Math.PI*r ;
System.out.println("Perimeter of Circle : "+perimeter);
System.out.println("Please enter number continue!");
s = Integer.parseInt(buff.readLine());
double area1 = java.lang.Math.PI*s*s;
System.out.println("Area of Circle : "+area1);
double perm =2*java.lang.Math.PI*s ;
System.out.println("Perimeter of Circle : "+perm);

System.out.print("would you like to Continue y or n:");
str=buff.readLine();
System.out.println("Good by");
}

}
catch(Exception e){
System.out.println("Error : "+e);
}

}
}
