Java / Regular expressions
What is the difference between matches() and find() in Java Regex?
matches() matches the expression against the entire string as it implicitly add a ^ at the start and $ at the end of your pattern, so it will not match substring or part of the string. ^ and $ are meta characters that represents start of the string and end of the string respectively.
find() matches the next occurrence within the substring that matches the regex.
public class PatternMatchExample { public static void main(String[] args) { Pattern p = Pattern.compile("[a-zA-Z]{9}"); Matcher m = p.matcher("www.javapedia.net"); System.out.println("Javapedia matched :" + m.matches()); System.out.println("Javapedia found :" + m.find()); } }
