IntelliJ IDEA problem

Question

Hi!
I'm trying to run this code on IntelliJ IDEA. But it's showing an error message. Any ideas why?
```java
package com.emilwallgren;
import java.io.Console;
public class Main {
public static void main(String[] args) {
// write your code here
    Console console = System.console();
    console.printf("hej");

}
}
```
the error message is:
Exception in thread "main" java.lang.NullPointerException
    at com.emilwallgren.Main.main(Main.java:10)
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)
    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)
    at java.lang.reflect.Method.invoke(Method.java:497)
    at com.intellij.rt.execution.application.AppMain.main(AppMain.java:140)
Process finished with exit code 1

IntelliJ does not support console normally. Take a look at the 'scanner' (http://docs.oracle.com/javase/7/docs/api/java/util/Scanner.html) class instead. Mr. Dennis discusses this a bit in his new course, Local Development Environments (https://teamtreehouse.com/library/local-development-environments). 
Hope it helps and happy coding,
Ken
