Public Methods
public static double avg (byte[] array)
public static double avg (float[] array)
public static double avg (short[] array)
public static double avg (int[] array)
public static double avg (long[] array)
public static double avg (Collection<? extends Number> collection)
public static double avg (double[] array)

public static boolean betweenExclusive (long value, long min, long max)
Check that a value is between two bounds (exclusive)
Parameters
| value | value |
|---|---|
| min | min bound |
| max | max bound |
Returns
- true if when value is in range ]min, max[
public static boolean betweenInclusive (long value, long min, long max)
Check that a value is between two bounds (inclusive)
Parameters
| value | value |
|---|---|
| min | min bound |
| max | max bound |
Returns
- true if when value is in range [min, max]
public static int minPositive (int... values)
Get the min of the values which is > 0. (for example when looking for min indexOf)
public static int moduloPositive (int a, int b)
Calculate the positive remainder of two integers.
Note: Java standard modulo operators specifies that the remainder will have the sign of the numerator. This method provides an alternate way to calculate the remainder, often-time more useful, by making sure that it remains positive.
Parameters
| a | any integer |
|---|---|
| b | a strictly positive integer |
Returns
- positive remainder
public static int pow (int a, int b)
Integer pow
