Matcher find() method in Java with Examples
The find() method of Matcher Class attempts to find the next subsequence of the input sequence that find the pattern. It returns a boolean value showing the same.
Syntax:
public boolean find()
Parameters: This method do not takes any parameter.
Return Value: This method returns a boolean value showing whether a subsequence of the input sequence find this matcher’s pattern
Below examples illustrate the Matcher.find() method:
Example 1:
// Java code to illustrate find() method import java.util.regex.*; public class GFG { public static void main(String[] args) { // Get the regex to be checked String regex = "Beginner"; // Create a pattern from regex Pattern pattern = Pattern.compile(regex); // Get the String to be matched String stringToBeMatched = "w3wiki"; // Create a matcher for the input String Matcher matcher = pattern .matcher(stringToBeMatched); // Get the subsequence // using find() method System.out.println(matcher.find()); } } |
Output:
true
Example 2:
// Java code to illustrate find() method import java.util.regex.*; public class GFG { public static void main(String[] args) { // Get the regex to be checked String regex = "GFG"; // Create a pattern from regex Pattern pattern = Pattern.compile(regex); // Get the String to be matched String stringToBeMatched = "GFGFGFGFGFGFGFGFGFG"; // Create a matcher for the input String Matcher matcher = pattern .matcher(stringToBeMatched); // Get the subsequence // using find() method System.out.println(matcher.find()); } } |
Output:
true
