so that it can be used in Java 6+.

compare(short s1,
short s2)
Compares
s1 and s2 . |
int compare(short s1, short s2)
s1
and s2
. Returns a negative value to indicate
that s1 < s2
, 0 to indicate that s1 == s2
, and a positive
value to indicate that s1 > s2
.
Implementations of this method must maintain the following invariants:
s(compare(x, y)) == -s(compare(y, x))
s(compare(x, y)) == s(compare(y, z))
→
s(compare(x, y)) == s(compare(x, z))
(transitivity)
compare(x, y) == 0
→
s(compare(x, z)) == s(compare(y, z))
∀ z
where s(x)
is defined as follows:
x < 0
: -1
x == 0
: 0
x > 0
: 1
s1
- the first short to compares2
- the second short to compares1
is less than, equal to, or greater than s2
