Parse a string to paragraphs

With this example we are going to demonstrate how to parse a String to paragraphs. In short, to parse a String to paragraphs you should:

  • Compile a given String regular expression to a Pattern with given flag set to multiline mode, using compile(string regex, int flags) API method of Pattern.
  • Use split(CharSequence input) API method of Pattern to split the given input sequence around matches of this pattern. It returns an array of strings.
  • Print the array’s elements.

Let’s take a look at the code snippet that follows:

package com.javacodegeeks.snippets.core;

import java.util.regex.Pattern;

public class ParsePar {

    public static void main(String[] argv) throws Exception {

  //CharSequence inputStr = "arrb"; // Mac

  //inputStr = "arnrnb"; // Windows

  CharSequence inputStr = "annb"; // Unix

  String pattern = "(?<=(rn|r|n))([ \t]*$)+";

  String[] par = Pattern.compile(pattern, Pattern.MULTILINE).split(inputStr);

  for (int i = 0; i < par.length; i++) {

String paragraph = par[i];







This was an example of how to parse a String to paragraphs in Java.
