Henri Yandell commented on LANG-238:
------------------------------------
Trying again:
NumberUtils.
public boolean allEqual( <T>[] array ) for T = long, int, short, byte
public boolean allEqual( <T>[] array, T error ) for T = float, double
BooleanUtils.
public boolean allEqual( boolean[] array )
// allTrue and allFalse worth having? They seem useful.
ObjectUtils.
public boolean allEqual( Object[] array ) [uses .equals()]
----
equals(...) seems a dangerous name to choose, so I did allEqual(...) above.
The contract from min(...) would imply that an IllegalArgumentException should
be thrown for:
allEqual( null )
allEqual( new int[0] )
I imagine that allEqual( new int[] { i } ) would be considered true rather than
throwing an exception; except for the case of Double.NaN and Float.NaN.
Should the double/float alternatives have an error value?

> It would be useful to add an equals() method like the current min and max
> methods which take an array type and determine if all the values are equal.
> I have found myself in need of this often. I have to retrieve objects from
> multiple data sources in parallel to build an array of complex object. To
> ensure
> validity, I always compare that my sub-retrievals returned the same number of
> objects as expected.
