Method Summary

Modifier and Type	Method and Description
public static List<Double>	Returns: a list view of the array asList(double... the array to back the list backingArray) Returns a fixed-size list backed by the specified array, similar to `Arrays#asList(Object[])`.
public static int	Returns: a negative value if `a` is less than `b`; a positive value if `a` is greater than `b`; or zero if they are equal compare(double the first `double` to compare a, double the second `double` to compare b) Compares the two specified `double` values.
public static double[]	Returns: a single array containing all the values from the source arrays, in order concat(double[]... zero or more `double` arrays arrays) Returns the values from each provided array combined into a single array.
public static double	constrainToRange(double the `double` value to constrain value, double the lower bound (inclusive) of the range to constrain `value` to min, double the upper bound (inclusive) of the range to constrain `value` to max) Returns the value nearest to `value` which is within the closed range `[min..max]`.
public static boolean	Returns: `true` if `array[i] == target` for some value of `i` contains(double[] an array of `double` values, possibly empty array, double a primitive `double` value target) Returns `true` if `target` is present as an element anywhere in `array`.
public static double[]	Returns: an array containing the values of `array`, with guaranteed minimum length `minLength` ensureCapacity(double[] the source array array, int the minimum length the returned array must guarantee minLength, int an extra amount to "grow" the array by if growth is necessary padding) Returns an array containing the same values as `array`, but guaranteed to be of a specified minimum length.
private static Pattern	fpPattern()
public static int	Returns: a hash code for the value hashCode(double a primitive `double` value value) Returns a hash code for `value`; equal to the result of invoking `((Double) value).hashCode()`.
public static int	Returns: the least index `i` for which `array[i] == target`, or `-1` if no such index exists. indexOf(double[] an array of `double` values, possibly empty array, double a primitive `double` value target) Returns the index of the first appearance of the value `target` in `array`.
private static int	indexOf(double[] array, double target, int start, int end)
public static int	indexOf(double[] the array to search for the sequence `target` array, double[] the array to search for as a sub-sequence of `array` target) Returns the start position of the first occurrence of the specified `target` within `array`, or `-1` if there is no such occurrence.
public static boolean	isFinite(double value) Returns `true` if `value` represents a real number.
public static String	join(String the text that should appear between consecutive values in the resulting string (but not at the start or end) separator, double... an array of `double` values, possibly empty array) Returns a string containing the supplied `double` values, converted to strings as specified by `Double#toString(double)`, and separated by `separator`.
public static int	Returns: the greatest index `i` for which `array[i] == target`, or `-1` if no such index exists. lastIndexOf(double[] an array of `double` values, possibly empty array, double a primitive `double` value target) Returns the index of the last appearance of the value `target` in `array`.
private static int	lastIndexOf(double[] array, double target, int start, int end)
public static Comparator<double[]>	lexicographicalComparator() Returns a comparator that compares two `double` arrays lexicographically.
public static double	Returns: the value present in `array` that is greater than or equal to every other value in the array max(double... a nonempty array of `double` values array) Returns the greatest value present in `array`, using the same rules of comparison as `Math#max(double, double)`.
public static double	Returns: the value present in `array` that is less than or equal to every other value in the array min(double... a nonempty array of `double` values array) Returns the least value present in `array`, using the same rules of comparison as `Math#min(double, double)`.
public static void	reverse(double[] array) Reverses the elements of `array`.
public static void	reverse(double[] array, int fromIndex, int toIndex) Reverses the elements of `array` between `fromIndex` inclusive and `toIndex` exclusive.
public static void	rotate(double[] array, int distance) Performs a right rotation of `array` of "distance" places, so that the first element is moved to index "distance", and the element at index `i` ends up at index `(distance + i) mod array.length`.
public static void	rotate(double[] array, int distance, int fromIndex, int toIndex) Performs a right rotation of `array` between `fromIndex` inclusive and `toIndex` exclusive.
public static void	sortDescending(double[] array) Sorts the elements of `array` in descending order.
public static void	sortDescending(double[] array, int fromIndex, int toIndex) Sorts the elements of `array` between `fromIndex` inclusive and `toIndex` exclusive in descending order.
public static Converter<String, Double>	stringConverter() Returns a serializable converter object that converts between strings and doubles using `Double#valueOf` and `Double#toString()`.
public static double[]	Returns: an array containing the same values as `collection`, in the same order, converted to primitives toArray(Collection<? extends Number> a collection of `Number` instances collection) Returns an array containing each value of `collection`, converted to a `double` value in the manner of `Number#doubleValue`.
public static Double	Returns: the floating point value represented by `string`, or `null` if `string` has a length of zero or cannot be parsed as a `double` value tryParse(String the string representation of a `double` value string) Parses the specified string as a double-precision floating point value.
