Description

Currently there are multiple Object based methods which could be replaced by a single generic method.

• public static Long[] nullToEmpty(final Long[] array)
• public static Integer[] nullToEmpty(final Integer[] array)
• public static Short[] nullToEmpty(final Short[] array)
• public static Character[] nullToEmpty(final Character[] array)
• public static Byte[] nullToEmpty(final Byte[] array)
• public static Double[] nullToEmpty(final Double[] array)
• public static Float[] nullToEmpty(final Float[] array)
• public static Boolean[] nullToEmpty(final Boolean[] array)

Recommendation, replace all of these with a single method that would also allow a defensive programming style when not using wrapped primitives.

• public static <T> T[] nullToEmpty(final T[] array)
