split

Desc：

Splits the provided text into an array, using whitespace as the separator. Whitespace is defined by Character#isWhitespace(char).

	string

split

Desc：

Splits the provided text into an array, separators specified. This is an alternative to using StringTokenizer.

The separator is not included in the returned String array. Adjacent separators are treated as one separator. For more control over the split use the StrTokenizer class.

A {@code null} input String returns {@code null}. A {@code null} separatorChars splits on whitespace.

tool.split(null, *)         = null
tool.split("", *)           =

name	type	desc
str	string
separatorChars	string
