    Default Cloneable interface

    If say:

    Java Code:
    public class Circle  extends GeometricObject implements Cloneable {
        private double radius;         
        protected Object clone() {
            Circle c = null;
            try {
                c = (Circle) super.clone();
            } catch (CloneNotSupportedException e) {
            return c;
    If try to go to source code of super.clone() method it points to Object class and that is ok, but I can't see any implementation of this method there, how object is beeing actually cloned.
    Where can I find that implementation?

    Default Re: Cloneable interface

    It's a native operation.
    It essentialy copies the contents of the object it's been called on (a shallow copy).
    Unless the object in question does not implement Cloneable in which case it throws an exception.

    This is all in the documentation for clone().
