Java Scanner nextShort() Method

The java Scanner nextShort() method scans the next token of the input as a short.An invocation of this method of the form nextShort() behaves in exactly the same way as the invocation nextShort(radix), where radix is the default radix of this scanner.

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

public short nextShort()

NA

This method returns the short scanned from the input

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

• NoSuchElementException − if input is exhausted

• IllegalStateException − if this scanner is closed

The Java 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.

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

public short nextShort(int radix)

radix − the radix used to interpret the token as a short value

This method returns the short scanned from the input

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

• NoSuchElementException − if input is exhausted

• IllegalStateException − if this scanner is closed

The following example shows the usage of Java Scanner nextShort() method to scan the next token as Short with default radix. We've created a scanner object using a given string. Then we checked each token to be Short and printed otherwise Not Found is printed along with scanned token. 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";

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

      while (scanner.hasNext()) {
         
         // check if the scanner's next token is a Short
         if(scanner.hasNextShort()){
            // print what is scanned
            System.out.println("Found: " + scanner.nextShort());		 
         } else {
            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: =
Found: 6

The following example shows the usage of Java Scanner nextShort() method to scan the next token as Short with given radix. We've created a scanner object using System.in class. Then we checked each token to be Short and printed otherwise Not Found is printed along with scanned token. 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);
         
      // check if the scanner's next token is a Short
      if(scanner.hasNextShort()){
         // print what is scanned
         System.out.println("Found: " + scanner.nextShort());		 
      } else {
         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 − (where we've entered 3)

3
Found: 3
