Hi there! The Picked Up Java Tools option message are not errors. They are informational messages about the memory settings on the JVM in Treehouse. It's nothing to be concerned with and has zero effect on your code. Here are a couple of posts by Treehouse staff where they elaborate on this:

Here is the error message that is telling you why it won't run:

Could not find or load main class Introduction.java .

According to this message, it cannot find "Introduction.java" and neither can I. When I open your snapshot, there is no Introduction.java. There is, however, a TreeStory.java. If you are 100% positive that you typed javac TreeStory.java and not javac Introduction.java then you may need to contact support at help@teamtreehouse.com. But before you do that, try and go up to View->Hide console and then View->Show console. This will refresh your console and clear any previous commands. This also has the benefit of putting you back in your home directory in case you somehow managed to navigate from there and that's why it can't find the files :smiley:

Hope this helps! :sparkles:

I can't run any code , for any code its giving the same error. I am using the workspace which is provided by Treehouse and its not working at all for all of my codes.

My guess is that you are just typing in the commands to run the program incorrectly. This is what you should run in the command-line:

javac TreeStory.java && java TreeStory

Hmm, strange. It works correctly for me. I am not sure what is wrong if that doesn't fix it.

Sup nurseiit-

In the notes he mentions an upgrade to the ide. This is a command that allows the jvm to start with more memory. JAVA_TOOL_OPTIONS: -Xmx128m. If you're getting an error here I'd test it out on another browser if that doesn't get it done you might look into something else locally. What's your workstation like?
