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 = "Geeks";          // Create a pattern from regex        Pattern pattern            = Pattern.compile(regex);          // Get the String to be matched        String stringToBeMatched            = "GeeksForGeeks";          // 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
