Matcher reset() Method in Java with Examples

Last Updated : 25 Apr, 2023

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 subpackage import java.util.regex.*;  // Main class public 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 subpackage import java.util.regex.*;  // Main class public 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
