public int hashCode()
ObjectThere are some requirements on this method which
subclasses must follow:
a.equals(b) is true, then
a.hashCode() == b.hashCode() must be as well.
However, the reverse is not necessarily true, and two
objects may have the same hashcode without being equal.Notice that since hashCode is used in
Hashtable and other hashing classes,
a poor implementation will degrade the performance of hashing
(so don't blindly implement it as returning a constant!). Also,
if calculating the hash is time-consuming, a class may consider
caching the results.
The default implementation returns
System.identityHashCode(this)
hashCode in interface PrincipalhashCode in class ObjectObject.equals(Object),
System.identityHashCode(Object)public boolean equals(Object o)
ObjectThere are some fairly strict requirements on this
method which subclasses must follow:
a.equals(b) and
b.equals(c), then a.equals(c)
must be true as well.a.equals(b) and
b.equals(a) must have the same value.a.equals(a) must
always be true.a.equals(null) must be false.a.equals(b) must imply
a.hashCode() == b.hashCode().
The reverse is not true; two objects that are not
equal may have the same hashcode, but that has
the potential to harm hashing performance.This is typically overridden to throw a ClassCastException
if the argument is not comparable to the class performing
the comparison, but that is not a requirement. It is legal
for a.equals(b) to be true even though
a.getClass() != b.getClass(). Also, it
is typical to never cause a NullPointerException.
In general, the Collections API (java.util) use the
equals method rather than the ==
operator to compare objects. However, IdentityHashMap
is an exception to this rule, for its own good reasons.
The default implementation returns this == o.

It is typical, but not required, to ensure that this method
never completes abruptly with a RuntimeException.
This method will be called when performing string
concatenation with this object. If the result is
null, string concatenation will instead
use "null".
