public final class Doubles
extends Object

A place for static default implementations of the new Java 8 static methods in the Double class.

Method Summary

Modifier and Type	Method and Description
static int	hashCode(double value) Returns a hash code for a double value; compatible with Double.hashCode().
static boolean	isFinite(double d) Returns true if the argument is a finite floating-point value; returns false otherwise (for NaN and infinity arguments).
static double	max(double a, double b) Returns the greater of two double values as if by calling Math.max.
static double	min(double a, double b) Returns the smaller of two double values as if by calling Math.min.
static double	sum(double a, double b) Adds two double values together as per the + operator.

Method Detail

hashCode

public static int hashCode(double value)

Returns a hash code for a double value; compatible with Double.hashCode().

Parameters:

value - the value to hash

Returns:

a hash code value for a double value.

Since:

1.8

sum

public static double sum(double a,
                         double b)

Adds two double values together as per the + operator.

See The Java™ Language Specification:
4.2.4 Floating-Point Operations

Parameters:

a - the first operand

b - the second operand

Returns:

the sum of a and b

Since:

1.8

max

public static double max(double a,
                         double b)

Returns the greater of two double values as if by calling Math.max.

Parameters:

a - the first operand

b - the second operand

Returns:

the greater of a and b

min

public static double min(double a,
                         double b)

Returns the smaller of two double values as if by calling Math.min.

Parameters:

a - the first operand

b - the second operand

Returns:

the smaller of a and b.

Since:

1.8

isFinite

public static boolean isFinite(double d)

Returns true if the argument is a finite floating-point value; returns false otherwise (for NaN and infinity arguments).

Parameters:

d - the double value to be tested

Returns:

true if the argument is a finite floating-point value, false otherwise.

Since:
