how to read an integer of DOUBLE datatype with type casting

please, tell me how to read an integer of DOUBLE data type using
1-readInt() with tpe casting.
2-any other approach

Code java:

---

ublic static void main(String [] args)
{
	Scanner read = new Scanner(System.in);
	double radius;
   Circle []c1 =new Circle[5];
 
    for (int i=0;i<c1.length;i++)
    {
  	  System.out.println("radius("+(i+1)+")= ");
  	  radius=read.nextInt();
  	  c1[i] = double new Circle2(radius);
  	  System.out.print("obj("+(i+1)+").Area= "+c1[i].area());
  	  System.out.print("obj("+(i+1)+").Area= "+c1[i].circum());
  	  System.out.print("obj("+(i+1)+").Area= "+c1[i].diam());
    }

---

c1[i] = new Circle2((double)radius);

However, Circle2 isn't defined anywhere.

Second, why not make radius a double to start with by

radius = readIn.nextDouble();

?

Perhaps you meant

c1[i] = new Circle(radius);

If there is a class called Circle2,

try type casting it

cl[i] = (Circle) new Circle2(radius);
