hashCode
public int hashCode()
- Description copied from class:
Object
- Returns a hash code value for the object. This method is
supported for the benefit of hashtables such as those provided by
java.util.Hashtable.
The general contract of hashCode is:
- Whenever it is invoked on the same object more than once during
an execution of a Java application, the 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.
- If two objects are equal according to the equals(Object)
method, then calling the
hashCode method on each of
the two objects must produce the same integer result.
- It is not required that if two objects are unequal
according to the
Object.equals(java.lang.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.)
- Overrides:
hashCode in class KeyPair
- Returns:
- a hash code value for this object.

equals
public boolean equals(Object obj)
- Description copied from class:
Object
- Indicates whether some other object is "equal to" this one.
The equals method implements an equivalence relation:
- It is reflexive: for any reference value
x,
x.equals(x) should return true.
- It is symmetric: for any reference values
x and
y, x.equals(y) should return
true if and only if y.equals(x) returns
true.
- It is transitive: for any reference values
x,
y, and z, if x.equals(y)
returns true and y.equals(z) returns
true, then x.equals(z) should return
true.
- It is consistent: for any reference values
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.
- For any non-null reference value
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).
- Overrides:
equals in class KeyPair
- Parameters:
obj - the reference object with which to compare.
- Returns:
true if this object is the same as the obj
argument; false otherwise.- See Also:
