The hitEnd() method of Matcher Class is used to check if this the matching of the pattern on this matcher has stopped or not. The matching ends when no more matched group is found in the matcher. This method returns a boolean value stating the same.
Syntax:
public boolean hitEnd()
Parameters: This method takes no parameters.
Return Value: This method returns a boolean value stating whether this matcher has finished matching or not.
Below examples illustrate the Matcher.hitEnd() method:
Example 1:
// Java code to illustrate hitEnd() 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 Geeks for For Geeks Geek";          // Create a matcher for the input String        Matcher matcher            = pattern.matcher(stringToBeMatched);          while (matcher.find()) {              System.out.println("Group matched: "                               + matcher.group());              // Check if the matching has ended            // using hitEnd() method            System.out.println("Has matching hit end: "                               + matcher.hitEnd());        }          // Check if the matching has ended        // using hitEnd() method        System.out.println("Has matching hit end: "                           + matcher.hitEnd());    }} |
Output:
Group matched: Geeks Has matching hit end: false Group matched: Geeks Has matching hit end: false Group matched: Geeks Has matching hit end: false Group matched: Geeks Has matching hit end: false Has matching hit end: true
Example 2:
// Java code to illustrate hitEnd() 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 FGF GFG GFG FGF";          // Create a matcher for the input String        Matcher matcher            = pattern.matcher(stringToBeMatched);          while (matcher.find()) {              System.out.println("Group matched: "                               + matcher.group());              // Check if the matching has ended            // using hitEnd() method            System.out.println("Has matching hit end: "                               + matcher.hitEnd());        }          // Check if the matching has ended        // using hitEnd() method        System.out.println("Has matching hit end: "                           + matcher.hitEnd());    }} |
Output:
Group matched: GFG Has matching hit end: false Group matched: GFG Has matching hit end: false Group matched: GFG Has matching hit end: false Group matched: GFG Has matching hit end: false Group matched: GFG Has matching hit end: false Group matched: GFG Has matching hit end: false Group matched: GFG Has matching hit end: false Has matching hit end: true
