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
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
