String
toString
()
Returns a string containing a concise, human-readable description of this
object. Subclasses are encouraged to override this method and provide an
implementation that takes into account the object's type and data. The
default implementation is equivalent to the following expression:
getClass().getName() + '@' + Integer.toHexString(hashCode())
See Writing a useful
toString method
if you intend implementing your own toString method.
Returns
- a printable representation of this object.
