Splitting the text using java.util.regex package

The split() method of the String class accepts a regular expression, splits the current input text into tokens and returns them as a string array.

Example

 Live Demo

import java.util.Scanner;
public class Example{
   public static void main(String[] args) {
      Scanner sc = new Scanner(System.in);
      System.out.println("Enter input text: ");
      String input = sc.nextLine();
      String[] strArray = input.split("\\d");
      for (int i=0; i<strArray.length; i++) {
         System.out.println(strArray[i]);
      }
   }
}

Output

Enter input text:

      System.out.println("Enter input text: ");
      String input = sc.nextLine();
      String regex = "\\d";
      //Creating a pattern object
      Pattern pattern = Pattern.compile(regex);
      String[] strArray = pattern.split(input);
      for (int i=0; i<strArray.length; i++) {
         System.out.println(strArray[i]);
      }
