```
    Copy from org.apache.commons.lang3.StringUtils
    Splits the provided text into an array with a maximum length, separators specified.
    
    The separator is not included in the returned String array. Adjacent separators are treated as one separator.
    
    A null input String returns null. A null separatorChars splits on whitespace.
    
    If more than max delimited substrings are found, the last returned string includes all characters after the first max - 1 returned strings (including separator characters).
```
 StringUtils.split(null, *, *)            = null
 StringUtils.split("", *, *)              = []

```
    参数:
    
    str - the String to parse, may be null
    
    separatorChars - the characters used as the delimiters, null splits on whitespace

    返回:
    
    an array of parsed Strings, null if null String input
  - splitByCharacterTypeCamelCase
```
public static String[] splitByCharacterTypeCamelCase(String str,

```
    Copy from org.apache.commons.lang3.StringUtils
    Splits a String by Character type as returned by java.lang.Character.getType(char). Groups of contiguous characters of the same type are returned as complete tokens, with the following exception: the character of type Character.UPPERCASE_LETTER, if any, immediately preceding a token of type Character.LOWERCASE_LETTER will belong to the following token rather than to the preceding, if any, Character.UPPERCASE_LETTER token.
```
 StringUtils.splitByCharacterTypeCamelCase(null)         = null
 StringUtils.splitByCharacterTypeCamelCase("")           = []
 StringUtils.splitByCharacterTypeCamelCase("ab de fg")   = ["ab", " ", "de", " ", "fg"]
 StringUtils.splitByCharacterTypeCamelCase("ab   de fg") = ["ab", "   ", "de", " ", "fg"]
 StringUtils.splitByCharacterTypeCamelCase("ab:cd:ef")   = ["ab", ":", "cd", ":", "ef"]
 StringUtils.splitByCharacterTypeCamelCase("number5")    = ["number", "5"]
 StringUtils.splitByCharacterTypeCamelCase("fooBar")     = ["foo", "Bar"]

 StringUtils.splitByCharacterTypeCamelCase("ASFRules")   = ["ASF", "Rules"]
 
```
    参数:
    
    str - the String to split, may be null
    
    camelCase - whether to use so-called "camel-case" for letter types
    
    返回:
    
    an array of parsed Strings, null if null String input
