public String toString()
Object
toString
method returns a
string that "textually represents" this object. The result should be a concise but informative
representation that is easy for a person to read. It is recommended that all subclasses override
this method.
The toString
method for class Object
returns a string consisting of the name of
the class of which the object is an instance, the at-sign character `@
', and the unsigned
hexadecimal representation of the hash code of the object. In other words, this method returns a
string equal to the value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
