split()

Example

Divide a string into an array containing its constituent substrings.

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 in Java divides a string into an array of substrings using a regular expression as the separator.

When a limit is defined, the resulting array won’t exceed this limit. The final element of the array holds the remaining portion of the string, which might include separators if the limit was reached.

Suggestion: Refer to the Java RegEx tutorial for a deeper understanding of regular expressions.

Syntax

One of the following:

public String[] split(String regex, int limit)

public String[] split(String regex)
