Java String split() method example.

The split(String regex, int limit) method of the String class. splits the current 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.

If the expression does not match any part of the input then the resulting array has just one element, namely this string.

Example

Live Demo

import java.lang.*;
public class StringDemo {
   public static void main(String[] args) {
      String str = "a d, m, i.n";
      String delimiters = "\\s+|,\\s*|\\.\\s*";

      //analysing the string
      String[] tokensVal = str.split(delimiters);

      //prints the count of tokens
      System.out.println("Count of tokens = " + tokensVal.length);

      for(String token : tokensVal) {
         System.out.print(token);
      }
      //analysing the string with limit as 3
      tokensVal = str.split(delimiters, 3);

      //prints the count of tokens
      System.out.println("\nCount of tokens = " + tokensVal.length);
      for(String token : tokensVal) {
         System.out.print(token);
      }
   }
}

Output

Count of tokens = 5
admin
Count of tokens = 3
adm, i.n
