Java.util.Scanner.nextShort() Method

Advertisements


Description

The java.util.Scanner.nextShort(int radix) method scans the next token of the input as a short. This method will throw InputMismatchException if the next token cannot be translated into a valid short value as described below. If the translation is successful, the scanner advances past the input that matched.

Declaration

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

public short nextShort(int radix)

Parameters

  • radix -- the radix used to interpret the token as a short value

Return Value

This method returns the short scanned from the input

Exception

  • InputMismatchException -- if the next token does not match the Integer regular expression, or is out of range

  • NoSuchElementException -- if input is exhausted

  • IllegalStateException -- if this scanner is closed

Example

The following example shows the usage of java.util.Scanner.nextShort() method.

package com.tutorialspoint;

import java.util.*;

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);

      // find the next short token and print it
      // loop for the whole scanner
      while (scanner.hasNext()) {

         // if the next is a short, print found and the short with radix 4
         if (scanner.hasNextShort()) {
            System.out.println("Found :" + scanner.nextShort(4));
         }

         // if no short is found, print "Not Found:" and the token
         System.out.println("Not Found :" + scanner.next());
      }

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

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

Not Found :Hello
Not Found :World!
Found :3
Not Found :+
Not Found :3.0
Not Found :=
Not Found :6.0
Not Found :true
