Method Detail

compare

public static int compare(int inValue1,
                          int inValue2)

Compares the absolute value of two ints. The equivalent of Integer's compareTo() but for int primitives.

compareAbs

public static int compareAbs(int inValue1,
                             int inValue2)

Compares the absolute value of two ints.

sum

public static double sum(List<? extends Number> inValues)

min

public static <N extends Number> N min(N inValue1,
                                       N inValue2)

A null-safe version of min() function in Integer, Float, Double, etc.

Type Parameters:

N - the type of Number object

Parameters:

inValue1 - first number

inValue2 - second number

Returns:

the minimum of the first and second numbers

max

public static <N extends Number> N max(N inValue1,
                                       N inValue2)

A null-safe version of max() function in Integer, Float, Double, etc.

Type Parameters:

N - the type of Number object

Parameters:

inValue1 - first number

inValue2 - second number

Returns:

the maximum of the first and second numbers
