Java Java Basics Getting Started with Java Introduction to Your Tools

Picked up JAVA_TOOL_OPTIONS: -Xmx128m?

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, my name is Abhishek!");

} }

after executing these commands the result was:

treehouse:~/workspace$ java Introductions Picked up JAVA_TOOL_OPTIONS: -Xmx128m Picked up _JAVA_OPTIONS: -Xmx128m Hello, my name is Abhishek! treehouse:~/workspace$

I did not understand what the 'Picked up JAVA_TOOL_OPTIONS: -Xmx128m' meant, this sentence did not appear in my teachers workspace.

Hi there! I received your request for assistance. Not to fear... this is not an error. It's just an informational message about some options set in the JVM about memory usage.

Here are a couple of posts by Treehouse staff where they elaborate on this:

Hope this helps! :sparkles:

Is there any way to get it to stop doing this? Or is it something I'll have to deal with for forever while using Treehouse?

Thanks!
