The delimiter() method ofjava.util.Scanner class returns the Pattern this Scanner is currently using to match delimiters.
Syntax:
public Pattern delimiter()
Return Value: The function returns the scanner’s delimiting pattern.
Below programs illustrate the above function:
Program 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(); }} |
Output:
Scanner String:
Geeksforgeeks has Scanner Class Methods
Delimiter being used in Scanner: \p{javaWhitespace}+
Program 2:
// 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); // 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 System.out.println("\nDelimiter being used in Scanner: " + scanner.delimiter()); // Close the scanner scanner.close(); }} |
Output:
Scanner String: Geeksforgeeks.has.Scanner.Class.Methods Delimiter being used in Scanner: .
