"Exception in thread "main" java.util.InputMismatchException"**

I have searched but i really can' t seem to find anything wrong in the code, please help!

The code compiles but, this is the error i get when i want to answer question 3:

Exception in thread "main" java.util.InputMismatchException
        at java.util.Scanner.throwFor(Unknown Source)
        at java.util.Scanner.next(Unknown Source)
        at java.util.Scanner.nextDouble(Unknown Source)
        at ForgetfulMachine.main(ForgetfulMachine.java:16)

And this is my code:

import java.util.Scanner;

public class ForgetfulMachine
{
    public static void main( String[] args )
    {
        Scanner keyboard = new Scanner(System.in);

        System.out.println( "What city is the capital of Germany?" );
        keyboard.next();

        System.out.println( "What is 6 divided by 2?" );
        keyboard.nextInt();

        System.out.println( "What is your favorite number between 0.0 and 1.0?" );
        keyboard.nextDouble();

        System.out.println( "Is there anything else you would like to tell me?" );
        keyboard.next();
    }
}

Solution

Scanner will throw this exception if the entry is in a format that is incorrect for the Scanner's Locale. Particularly, in your case, if the wrong decimal separator is used. Both . and , are common locale-specific decimal separators.

To find out what the decimal separator is for your default locale you may use:

System.out.println(
    javax.text.DecimalFormatSymbols.getInstance().getDecimalSeparator()
);
