I tried the exercise of the first lesson. but It doesn't work for. Help me

import java.io.Console;

public class Introductions {

public static void main(String[] args) {
    Console console = System.console();
    // Welcome to the Introductions program!  Your code goes below here
  console.printf("Hello");

} }

What wrong with the code above? Please help me. Whenever I try, the error show as below.

treehouse:~/workspace$ javac Introductions.java
Picked up JAVA_TOOL_OPTIONS: -Xmx128m
Picked up _JAVA_OPTIONS: -Xmx128m
treehouse:~/workspace$ javac Introductions.java
Picked up JAVA_TOOL_OPTIONS: -Xmx128m

Hi John Smith

You've got the code correct, just not using the correct console command. You are using javac and including the extension of the Class. Instead, you need to use java (no "c") and not include the extension.
So, is should be java Introductions

Craig explains this in the video at timestamp 6:01 - 6:15.

Keep Coding! :dizzy:
