maxFloat

public static float maxFloat(float... array)

maxLong

public static long maxLong(long... array)

maxDouble

public static double maxDouble(double... array)

min

public static int min(int... array)

minFloat

isOutOfBounds

public static boolean isOutOfBounds(int index,
                                    int length,
                                    int capacity)

Determine if the requested index and length will fit within capacity.

参数:

index - The starting index.

length - The length which will be utilized (starting from index).

capacity - The capacity that index + length is allowed to be within.

返回:

true if the requested index and length will fit within capacity. false if this would result in an index out of bounds exception.
