Java regex program to split a string with line endings as delimiter

In windows "\r\n" acts as the line separator. The regular expression "\\r?\\n" matches the line endings.

The split() method of the String class accepts a value representing a regular expression and splits the current string into array of tokens (words), treating the string between the occurrence of two matches as one token.

Therefore, if you want to split a string with line endings as delimiter, invoke the split() method on the input string by passing the above specified regular expression as a parameter.

Example

 Live Demo

import java.util.Scanner;
public class RegexExample {
   public static void main(String[] args) {
      System.out.println("Enter your input string: ");
      Scanner sc = new Scanner(System.in);
      String input = " sample text \r\n line1 \r\n line2 \r\n line3 \r\n line4";
      String[] strArray = input.split("\\r?\\n");
      for (int i=0; i<strArray.length; i++) {
         System.out.println(strArray[i]);
      }
   }
}

Output

Enter your input string:
sample text
line1
line2
line3
line4
