❮ String Methods
Example
String myStr = "Split a string by spaces, and also punctuation.";
String regex = "[,\\.\\s]";
String[] myArray = myStr.split(regex);
for (String s : myArray) {
System.out.println(s);
}Definition and Usage
The split() method splits a string into an array of substrings using a regular expression as the separator.
If a limit is specified, the returned array will not be longer than the limit. The last element of the array will contain the remainder of the string, which may still have separators in it if the limit was reached.

See the Java RegEx tutorial to learn about regular expressions.
