equals: Compares an object with another
Description
Compares an object with another and returns TRUE
if they are equal.
The equal property must be
1) reflexive, i.e. equals(o1,o1)
should be TRUE
.
2) symmetric, i.e. equals(o1,o2)
is TRUE
if and only
if equals(o2,o1)
is TRUE
.
3) transitive, i.e. equals(o1,o2)
is TRUE
and
equals(o2,o3)
is TRUE
, then equals(o1,o3)
should
be TRUE
.
5) consistent, i.e. equals(o1,o2)
should return the same
result on multiple invocations as long as nothing has changed.
6) equals(o1,
NULL
)
should return FALSE
.
