El método radix() de la clase java.util.Scanner devuelve el radix predeterminado de este escáner.
Sintaxis:
public int radix()
Valor devuelto: esta función devuelve la raíz predeterminada de este escáner.
Los siguientes programas ilustran la función anterior:
Programa 1:
// Java program to illustrate the
// radix() 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 methods";
// create a new scanner
// with the specified String Object
Scanner scanner = new Scanner(s);
// print a line of the scanner
System.out.println("Scanner String:\n"
+ scanner.nextLine());
// print the default radix
System.out.println("Default Radix value: "
+ scanner.radix());
// close the scanner
scanner.close();
}
}
Producción:
Scanner String: Geeksforgeeks has Scanner methods Default Radix value: 10
Programa 2:
// Java program to illustrate the
// radix() method of Scanner class in Java
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
throws Exception
{
String s = "Geeksforgeeks";
// create a new scanner
// with the specified String Object
Scanner scanner = new Scanner(s);
// print a line of the scanner
System.out.println("Scanner String: "
+ scanner.nextLine());
// print the default radix
System.out.println("Default Radix value: "
+ scanner.radix());
// change the radix of this scanner
scanner.useRadix(30);
System.out.println("Radix changed to 30");
// print the default radix
System.out.println("Default Radix value: "
+ scanner.radix());
// close the scanner
scanner.close();
}
}
Producción:
Scanner String: Geeksforgeeks Default Radix value: 10 Radix changed to 30 Default Radix value: 30
