  • toString

    public String toString()

    Description copied from class: Object
    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.

    Overrides:

    toString in class Object

    Returns:

    a printable representation of this object.
