El método delimiter() de la clase java.util.Scanner devuelve el patrón que este escáner está utilizando actualmente para hacer coincidir los delimitadores.
Sintaxis:
public Pattern delimiter()
Valor devuelto: la función devuelve el patrón de delimitación del escáner.
Los siguientes programas ilustran la función anterior:
Programa 1:
// Java program to illustrate the
// delimiter() method of Scanner class in Java
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
throws Exception
{
String s = "Geeksforgeeks has Scanner Class Methods";
// create a new scanner
// with the specified String Object
Scanner scanner = new Scanner(s);
// prints the next line of the string
System.out.println("Scanner String: \n"
+ scanner.nextLine());
// print the delimiter this scanner is using
System.out.println("\nDelimiter being used in Scanner: "
+ scanner.delimiter());
// Close the scanner
scanner.close();
}
}
Producción:
Scanner String:
Geeksforgeeks has Scanner Class Methods
Delimiter being used in Scanner: \p{javaWhitespace}+
Programa 2:

// with the specified String Object
Scanner scanner = new Scanner(s);
// Set the delimiter to "."
scanner.useDelimiter(".");
// prints the next line of the string
System.out.println("Scanner String: \n"
+ scanner.nextLine());
// print the delimiter this scanner is using

}
}
