public final class Longs
extends java.lang.Object
Long class.| Modifier and Type | Method and Description |
|---|---|
static int |
compare(long x,
long y)
Compares two
long values numerically. |
static int |
compareUnsigned(long x,
long y)
Compares two
long values numerically treating the values
as unsigned. |
static long |
divideUnsigned(long dividend,
long divisor)
Returns the unsigned quotient of dividing the first argument by
the second where each argument and the result is interpreted as
an unsigned value.
|
static int |
hashCode(long value)
Returns a hash code for a
long value; compatible with
Long.hashCode(). |
static long |
max(long a,
long b)
Returns the greater of two
long values
as if by calling Math.max. |
static long |
min(long a,
long b)
Returns the smaller of two
long values
as if by calling Math.min. |
static long |
remainderUnsigned(long dividend,
long divisor)
Returns the unsigned remainder from dividing the first argument
by the second where each argument and the result is interpreted
as an unsigned value.
|
static long |
sum(long a,
long b)
Adds two
long values together as per the + operator. |
public static int hashCode(long value)
long value; compatible with
Long.hashCode().value - the value to hashlong value.public static long divideUnsigned(long dividend,
long divisor)
Note that in two's complement arithmetic, the three other
basic arithmetic operations of add, subtract, and multiply are
bit-wise identical if the two operands are regarded as both
being signed or both being unsigned. Therefore separate addUnsigned, etc. methods are not provided.
dividend - the value to be divideddivisor - the value doing the dividingremainderUnsigned(long, long)public static int compare(long x,
long y)
long values numerically.
The value returned is identical to what would be returned by:
Long.valueOf(x).compareTo(Long.valueOf(y))
x - the first long to comparey - the second long to compare0 if x == y;
a value less than 0 if x < y; and
a value greater than 0 if x > ypublic static int compareUnsigned(long x,
long y)
long values numerically treating the values
as unsigned.x - the first long to comparey - the second long to compare0 if x == y; a value less
than 0 if x < y as unsigned values; and
a value greater than 0 if x > y as
unsigned valuespublic static long remainderUnsigned(long dividend,
long divisor)

long b)
long values
as if by calling Math.max.a - the first operandb - the second operanda and bBinaryOperatorpublic static long min(long a,
long b)
