Extracted text: public class Test { public static void main (String [] args) { Object circlel = new Circle (); Object circle2 = new Circle (); System.out.println(circlel.equals (circle2)); class Circle { double radius; class Circle { double radius; public boolean equals (Circle circle) { public boolean equals (Object o) { return this.radius = ( (Circle)o).radius; return this.radius = circle.radius;


Extracted text: b. When running Test using the Circle class in (b), if circlel.equals (circle2) in the Test class is replaced by circlel.equals ("Binding"), this will cause a casting exception, because o (as a String) cannot be casted into Circle . Reimplement the equals method in (b) to avoid this exception when comparing circle with a non-circle object.
