Java Scanner nextShort() Method

The nextShort() is a Java Scanner class method which is used to scan the next token of the input as a Short. There is two different types of Java nextShort() method which can be differentiated depending on its parameter. These are:

Java Scanner nextShort() Method
Java Scanner nextShort(int radix) Method

nextShort() Method

This is a Java Scanner class method which is used to scan the next token of the input as a Short in the default radix.

nextShort(int radix) Method

This is an inbuilt method of Java Scanner class which is used to scan the next token of the input as a Short in the specified radix.

Syntax

Following is the declaration of nextShort() method:

public Short nextShort()
public Short nextShort(int radix)

Parameter

DataType	Parameter	Description	Required/Optional
int	radix	It is used to interpret the token as a short value.	Required

Returns

The nextShort() method returns the Short value scanned from the input.

Exceptions

IllegalStateException- This method throws exception if the innvocation is done after the scanner has been closed.

IllegalArgumentException- It throws this exception if the specified radix is out of range.

InputMismatchException- It throws this exception if the next token does not match the Integer regular expression, or is out of range.

Compatibility Version

Java 1.5 and above

Example 1

import java.util.*;
public class ScannerNextShortExample1 {  
	public static void main(String[] args) {
		Scanner input = new Scanner(System.in);
		System.out.print("Enter the Number you want: ");
	      Short num = input.nextShort();
	      System.out.println("Output value: "+(num * (num + 2)) / 2);
	      input.close();
	      }
}

Output:

Enter the Number you want: 40
Output value: 840

Example 2

import java.util.*;
public class ScannerNextShortExample2 {  
	public static void main(String[] args) {
		  String str = "Facebook.com 13 + 13 = 26.0 true ";
	      Scanner scanner = new Scanner(str);
	      while (scanner.hasNext()) {
	         if (scanner.hasNextShort()) {
	            System.out.println("Found :" + scanner.nextShort(4));
	         }
	         System.out.println("Not Found :" + scanner.next());
	      }
	      scanner.close();
	}
}

Output:

Not Found :Facebook.com
Found :7
Not Found :+
Found :7
Not Found :=
Not Found :26.0
Not Found :true

Example 3

import java.util.*;
public class ScannerNextShortExample3 {  
	public static void main(String[] args) {
		 String str = "JavaTpoint.com 13 + 13 = 26.0 true ";
	      Short sh = 12345;
	      str = str + sh;
	      Scanner scanner = new Scanner(str);
	      while (scanner.hasNext()) {
	         System.out.println("Not Found: " + scanner.next());
	         if (scanner.hasNextShort()) {
	            System.out.println("Found: " + scanner.nextShort());
	         }
	      }
	      scanner.close();
	}
}

Output:

Not Found: JavaTpoint.com
Found: 13
Not Found: +
Found: 13
Not Found: =
Not Found: 26.0
Not Found: true
Found: 12345

Example 4

import java.util.*;
public class ScannerNextShortExample4 {  
	public static void main(String[] args) {
		//Initialize the scanner
		Scanner scan = new Scanner("5555 B35 -2555 -755 51D");
		while(scan.hasNext()){
			//Printing int tokens of specified base
			System.out.println(scan.nextShort(555));
		}
		scan.close();
	}
}

Output:

Exception in thread "main" java.lang.IllegalArgumentException: radix:555
	at java.base/java.util.Scanner.setRadix(Scanner.java:1368)
	at java.base/java.util.Scanner.nextShort(Scanner.java:2114)
	at myPackage.ScannerNextShortExample4.main(ScannerNextShortExample4.java:9)
