示例1: getExplodedArray
/**
* Take a concatenated String and return the passed String array of all
* elements in the passed string, using specified separator char.
*
* @param cSep
* The separator to use.
* @param sElements
* The concatenated String to convert. May be <code>null</code> or
* empty.
* @param nMaxItems
* The maximum number of items to explode. If the passed value is ≤
* 0 all items are used. If max items is 1, than the result string is
* returned as is. If max items is larger than the number of elements
* found, it has no effect.
* @return The passed collection and never <code>null</code>.

示例2: getSplitToArray
/**
* Split the passed text with the given regular expression. If you do not need
* a regular expression, {@link StringHelper#getExploded(String, String)} is a
* faster option.
*
* @param sText
* The text to be split. May be <code>null</code>.
* @param sRegEx
* The regular expression to use for splitting. May neither be
* <code>null</code> nor empty.
* @return An empty array if the text is <code>null</code>, a non-
* <code>null</code> array otherwise. If both text and regular
* expression are <code>null</code> an empty array is returned as well
* since the text parameter is checked first.
