String.split(String regex, int limit)


public String[] split(String regex,
                      int limit)
Splits this string around matches of the given regular expression.The array returned by this method contains each substring of this string that is terminated by another substring that matches the given expression or is terminated by the end of the string. The substrings in the array are in the order in which they occur in this string. If the expression does not match any part of the input then the resulting array has just one element, namely this string.
The limit parameter controls the number of times the pattern is applied and therefore affects the length of the resulting array. If the limit n is greater than zero then the pattern will be applied at mostn - 1 times, the array's length will be no greater than n, and the array's last entry will contain all input beyond the last matched delimiter. If n is non-positive then the pattern will be applied as many times as possible and the array can have any length. If n is zero then the pattern will be applied as many times as possible, the array can have any length, and trailing empty strings will be discarded.
The string "boo:and:foo", for example, yields the following results with these parameters:
:2{ "boo", "and:foo" }
:5{ "boo", "and", "foo" }
:-2{ "boo", "and", "foo" }
o5{ "b", "", ":and:f", "", "" }
o-2{ "b", "", ":and:f", "", "" }
o0{ "b", "", ":and:f" }

It is equal as Pattern.compile(regex).split(str, n)
