Java Scanner nextShort() Method
Description
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.
Declaration
Following is the declaration for java.util.Scanner.nextShort() method
public short nextShort()
Parameters
NA
Return Value
This method returns the short scanned from the input
Exception
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
Java Scanner nextShort(int radix) Method
Description
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.
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 Shorteger regular expression, or is out of range
NoSuchElementException − if input is exhausted
IllegalStateException − if this scanner is closed
Getting Next Token as Short of a Scanner on String Example
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(); } }
Output
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
Getting Next Token as Short with Radix of a Scanner on String Example
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 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(4)){ // print what is scanned System.out.println("Found: " + scanner.nextShort(4)); } else { System.out.println("Not Found: " + scanner.next()); } } // close the scanner scanner.close(); } }
Output
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
Getting Next Token as Short of a Scanner on User Input Example
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(); } }
Output
Let us compile and run the above program, this will produce the following result − (where we've entered 3)
3 Found: 3
