        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());

    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);
