In this tutorial, we are going to see how to get string between two tags in Java. Regular Expressions or Regex is an API for defining patterns that can be used to find, manipulate, and edit a string in Java. Regex is widely used to define constraints. Regular expressions are provided under java.util package.

public class Main 
{
  public static void main(String[]args) 
  {
      Pattern p = Pattern.compile("<b>(.+?)</b>", Pattern.DOTALL);
      Matcher m = p.matcher("<b>String I want to extract</b>");
      m.find();
      System.out.println(m.group(1));
