clone
public Object clone()
This method may be called to create a new copy of the
Object. The typical behavior is as follows:
o == o.clone()
is falseo.getClass() == o.clone().getClass()
is trueo.equals(o)
is true
However, 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());
}
}
- clone in interface Object
toString
public String toString()
Convert this Object to a human-readable String.
There are no limits placed on how long this String
should be or what it should contain. We suggest you
make it as intuitive as possible to be able to place
it into
System.out.println()
and such.
It is typical, but not required, to ensure that this method
never completes abruptly with a
RuntimeException
.
This method will be called when performing string
concatenation with this object. If the result is
null
, string concatenation will instead
use
"null"
.
The default implementation returns
getClass().getName() + "@" +
Integer.toHexString(hashCode())
.
- toString in interface Object
- the String representing this Object, which may be null
