El método hitEnd() de Matcher Class se usa para verificar si la coincidencia del patrón en este comparador se ha detenido o no. La coincidencia finaliza cuando no se encuentran más grupos coincidentes en el comparador. Este método devuelve un valor booleano que indica lo mismo.
Sintaxis:
public boolean hitEnd()
Parámetros: Este método no toma parámetros.
Valor devuelto: este método devuelve un valor booleano que indica si este comparador ha terminado de emparejar o no.
Los siguientes ejemplos ilustran el método Matcher.hitEnd():
Ejemplo 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());
}
}
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
Ejemplo 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());
}
}
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
