InputMismatchException in thread "main"

Question

First of all i am compete noob in Java. I tried to get the user input. Eclipse shows this error whenever i try to type double variable:

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 lesson1.MyClass.main(MyClass.java:10)

This is my code so far:

import java.util.Scanner;

public class MyClass {

public static void main(String[] args) {
Scanner scan1 = new Scanner(System.in);
System.out.println("Enter some decimal value");
double userInput = scan1.nextDouble();
System.out.println("The entered value is ");
System.out.print(userInput);
}

There seems to be nothing noticably wrong with the code, it is likely that the scanner can not parse a double from your input. Try entering a number and then text and compare results — Nic, Feb 05 '17 at 09:46
in console, write number value like 11.111 or something, if you write String then it will throw error like this. — yash, Feb 05 '17 at 09:48

Above codes are right! You must ensure input decimal, such as 12.3 Below is my test： Test Result
