Parameters: This method do not takes any parameter.

Return Value: This method returns a boolean value showing whether this pattern matches with this matcher or not.

Below examples illustrate the Matcher.matches() method:

Example 1:

// Java code to illustrate matches() 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 result state
        // using matches() method
        System.out.println("Result: "
                           + matcher.matches());
    }
}

Output:

Result: false

Example 2:

// Java code to illustrate matches() 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 result state
        // using matches() method
        System.out.println("Result: "
                           + matcher.matches());
    }
}

Output:

Result: false
