Hi!
I'm trying to run this code on IntelliJ IDEA. But it's showing an error message. Any ideas why?
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' class instead. Mr. Dennis discusses this a bit in his new course, Local Development Environments.
Hope it helps and happy coding,
