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: .
