The reset() method of Matcher Class is used to reset this matcher, in order to understand it better it is recommended to have prior knowledge of Pattern and Matcher class in java regex sub-package. Here we will be illustrating it with help of Java programs.
Syntax:
public Matcher reset()
Parameters: This method does not take any parameters.
Return Value: This method returns this Matcher after being reset.
Example 1:
Java
// Java Program to illustrate reset() method// of Matcher class// Importing class from java.util.regex package// where regex is a subpackageimport java.util.regex.*;// Main classpublic class GFG { // Main driver method public static void main(String[] args) { // Getting the regex to be checked // taking via string input String regex = "Geeks"; // Creating a pattern from regex // using Pattern class Pattern pattern = Pattern.compile(regex); // Getting the String to be matched String stringToBeMatched = "GeeksForGeeks"; // Creating a matcher for the input String // using Matcher class Matcher matcher = pattern.matcher(stringToBeMatched); // Resetting the Matcher using reset() method matcher = matcher.reset(); // Getting the current matcher state // using tomatchResult() method and // printing it System.out.println(matcher.toMatchResult()); }} |
Output
java.util.regex.Matcher$ImmutableMatchResult@448139f0
Example 2:
Java
// Java Program to Illustrate reset() method// of Matcher class// Importing class from java.util.regex package// where regex is a subpackageimport java.util.regex.*;// Main classpublic class GFG { // Main driver method public static void main(String[] args) { // Getting the regex to be checked String regex = "GFG"; // Creating a pattern from regex Pattern pattern = Pattern.compile(regex); // Getting the String to be matched String stringToBeMatched = "GFGFGFGFGFGFGFGFGFG"; // Creating a matcher for the input String Matcher matcher = pattern.matcher(stringToBeMatched); // Resetting the Matcher // using reset() method matcher = matcher.reset(); // Getting the current matcher state // using toMatchResult() method System.out.println(matcher.toMatchResult()); }} |
Output
java.util.regex.Matcher$ImmutableMatchResult@448139f0
