public native int hashCode()
Returns
a hash code value for this object.
Description
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. 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
method, then calling the hashCode method on each of the
two objects must produce the same integer result.
