public boolean equals(java.lang.Object o)
The equals
method implements an equivalence relation:
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 object is modified.
x
,
x.equals(null)
should return false
.
The equals method for class Object
implements
the most discriminating possible equivalence relation on objects;
that is, for any 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
).
o
- the reference object with which to compare.
true
if this object is the same as the obj
argument; false
otherwise.Boolean.hashCode()
public int hashCode()
java.util.Hashtable
.
The general contract of hashCode
is:
hashCode
method on each of
the two objects must produce the same integer result.
Object.equals(Object)
method, then calling the 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 hashtables.
As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)
Object.equals(Object)
public java.lang.String toString()
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())
