According to the Java Language Specification, there is a contract between ``++equals(Object)++`` and ``++hashCode()++``:
|
|
|
|
|
|
____
|
|
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 ``++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.
|
|
|
|
____
|
|
|
|
In order to comply with this contract, those methods should be either both inherited, or both overridden.
