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)
