Java Scanner radix() Method

The java Scanner radix() method returns this scanner's default radix.

Following is the declaration for java.util.Scanner.radix() method

public int radix()

NA

This method returns the default radix of this scanner

NA

The following example shows the usage of Java Scanner radix() method to get the radix of the scanner object. We've created a scanner object using a given string. Then we printed the string using nextLine() and radix using radix() method. In the end scanner is closed using close() method.

package com.tutorialspoint;

import java.util.Scanner;

public class ScannerDemo {
   public static void main(String[] args) {

      String s = "Hello World! 3 + 3.0 = 6.0 true ";

      // create a new scanner with the specified String Object
      Scanner scanner = new Scanner(s);

      // print a line of the scanner
      System.out.println(scanner.nextLine());

      // print the default radix
      System.out.println(scanner.radix());

      // close the scanner
      scanner.close();
   }
}

Let us compile and run the above program, this will produce the following result −

Hello World! 3 + 3.0 = 6.0 true 
10

The following example shows the usage of Java Scanner radix() method to get the radix of the scanner object. We've created a scanner object using a given string. We've set the radix as 4 using useRadix() method. Then we printed the string using nextLine() and radix using radix() method. In the end scanner is closed using close() method.

package com.tutorialspoint;

import java.util.Scanner;

public class ScannerDemo {
   public static void main(String[] args) {

      String s = "Hello World! 3 + 3.0 = 6.0 true ";

      // create a new scanner with the specified String Object
      Scanner scanner = new Scanner(s);
	  
      // use a new radix
      scanner.useRadix(4);

      // print a line of the scanner
      System.out.println(scanner.nextLine());

      // print the default radix
      System.out.println(scanner.radix());

      // close the scanner
      scanner.close();
   }
}

Let us compile and run the above program, this will produce the following result −

Hello World! 3 + 3.0 = 6.0 true 
4

The following example shows the usage of Java Scanner radix() method to get the radix of the scanner object. We've created a scanner object using System.in class. Then we printed the string using nextLine() and radix using radix() method. In the end scanner is closed using close() method.

package com.tutorialspoint;

import java.util.Scanner;

public class ScannerDemo {
   public static void main(String[] args) {

      // create a new scanner with System input
      Scanner scanner = new Scanner(System.in);

      // print a line of the scanner
      System.out.println(scanner.nextLine());

      // print the default radix
      System.out.println(scanner.radix());

      // close the scanner
      scanner.close();
   }
}

Let us compile and run the above program, this will produce the following result − (We've entered 3.)
