The equals method implements an equivalence relation
on non-null object references:
x, x.equals(x) should return
true.
x and y, x.equals(y)
should return true if and only if
y.equals(x) returns true.
x, y, and z, if
x.equals(y) returns true and
y.equals(z) returns true, then
x.equals(z) should return true.
x and y, multiple invocations of
x.equals(y) consistently return true
or consistently return false, provided no
information used in equals comparisons on the
objects is modified.
x,
x.equals(null) should return false.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
equals method for class Object implements
the most discriminating possible equivalence relation on objects;
that is, for any non-null reference values x and
y, this method returns true if and only
if x and y refer to the same object
(x == y has the value true).
In other words, under the reference equality equivalence
relation, each equivalence class only has a single element.hashCode method, which states
that equal objects must have equal hash codes.obj - the reference object with which to compare.true if this object is the same as the obj
argument; false otherwise.Returns the name.
Returns the value.
Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.
The general contract of hashCode is:
hashCode method
must consistently return the same integer, provided no information
used in equals comparisons on the object is modified.
This integer need not remain consistent from one execution of an
application to another execution of the same application.
hashCode method on each of the two objects must produce the
same integer result.
hashCode method on each of the two objects
must produce distinct integer results. However, the programmer
should be aware that producing distinct integer results for
unequal objects may improve the performance of hash tables.
hashCode method defined
by class Object returns distinct integers for distinct objects.Returns a string representation of the 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 string output is not necessarily stable over time or across
JVM invocations.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())
