Scanner double value- InputMismatchException

I am trying to prompt user to enter x coordinate but when I write a decimal number such as 2.1 as an input this is caused a problem .How can I fix the problem?

     import java.util.Scanner;

     public class TwoRetangles{

     public static void main(String[]args){

     Scanner input=new Scanner(System.in);

      System.out.print("Enter the center x coordinate of retangle = ");

      double x1=input.nextDouble();

      }
}

--------------------Configuration: --------------------

      Enter the center x coordinate of retangle = 2.1

     Exception in thread "main" java.util.InputMismatchException

Your code works for me.. Scanner is tied to your system settings I believe, so if its not for US you couldn't use a decimal like 2.1.

If that is the case, do

Scanner input = new Scanner(System.in).useLocale(Locale.US);

You would need to import java.util.*;

There is no error.It is working fine in my system.Make sure you compiled it right.It is accepting the value.I tried this code and it is printing 2.1:

import java.util.Scanner;

public class TwoRetangles{

   public static void main(String[]args){

   Scanner input=new Scanner(System.in);

   System.out.print("Enter the center x coordinate of retangle = ");

   double x1=input.nextDouble();

   System.out.print(x1);

      }
}
