下面的示例说明Matcher.toMatchResult()方法：

示例1:

// Java code to illustrate toMatchResult() 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 toMatchResult() method 
        System.out.println("Result: "
                           + matcher.toMatchResult()); 
    } 
}

输出：

Result: java.util.regex.Matcher[pattern=Geeks region=0, 13 lastmatch=]

示例2:

// Java code to illustrate toMatchResult() 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 toMatchResult() method 
        System.out.println("Result: "
                           + matcher.toMatchResult()); 
    } 
}

输出：

Result: java.util.regex.Matcher[pattern=GFG region=0, 19 lastmatch=]
