public Object clone() throws CloneNotSupportedException
Object
o == o.clone()
is falseo.getClass() == o.clone().getClass()
is trueo.equals(o)
is trueHowever, these are not strict requirements, and may
be violated if necessary. Of the three requirements, the
last is the most commonly violated, particularly if the
subclass does not override Object.equals(Object)
.
If the Object you call clone() on does not implement
Cloneable
(which is a placeholder interface), then
a CloneNotSupportedException is thrown. Notice that
Object does not implement Cloneable; this method exists
as a convenience for subclasses that do.
Object's implementation of clone allocates space for the new Object using the correct class, without calling any constructors, and then fills in all of the new field values with the old field values. Thus, it is a shallow copy. However, subclasses are permitted to make a deep copy.
All array types implement Cloneable, and override
this method as follows (it should never fail):
public Object clone() { try { super.clone(); } catch (CloneNotSupportedException e) { throw new InternalError(e.getMessage()); } }
